Can you legally fist fight in Texas?
Mutual combat is also legal in Texas. Like Washington state, people who wish to duke it out in Texas must do so under the watchful eye of a police officer. Considering that Texas law allows people to carry swords in public, it's hardly surprising that consensual fistfights are legal.
Texas Penal Code states that you are justified in using force against another person when you believe it is necessary to protect yourself. Specifically, you are entitled to use force to the same degree as the other party's use or attempted use of unlawful force.
A consensual fight is not necessarily an assault as the parties are consenting to the physical contact. Consent can be negated or vitiated where the force causes bodily harm and was intended to be caused. Thus, where serious bodily harm was intended and caused, there can be no consent.
Fighting itself is not illegal if both parties consent to it, but that does not mean you won't get charged with some version of a crime such as Disorderly Conduct or Assault. Whether your actions are legal, or illegal depends on the circumstance – reason, location, force, etc.
Texas permits the use of force without a duty to retreat, also known as “stand your ground” laws. If you injure or kill someone in self-defense, you need a skilled criminal defense lawyer.
In Texas, the law permits two individuals to engage in mutual combat. Under Texas Penal Code section 22.06, a person is engaged in mutual combat if the contact did not cause serious bodily injury or threaten to cause injury, or if the alleged victim took part despite knowing the risk because of their profession.
For adults age 18 and over, it is lawful to carry a knife in most places throughout Texas, whether open or concealed carry. As the name suggests, however, “location-restricted knives” are prohibited from being carried in certain locations.
Can you hit someone if they provoke you? Just because someone insulted you or said something rude or mean doesn't mean you have the right to hit them. However, if physical harm is imminent or they've already hit you once, you may have a legal right to self defence and can hit them back.
Recklessness. A reckless act is one that is committed, not necessarily with intent to harm another, but without regard for the outcome. For example, pushing someone out of the way in a crowd so that you can get through, without intending to injure the person, could be an assault if the person falls and is injured.
Texas Penal Code § 46.01 states that Texans can own and openly carry knives (switchblades, pocket knives, butterfly knives), spears, swords and throwing stars.
Can I hit someone for fighting words?
Even though "fighting words" aren't protected as free speech, they're still not a legal justification for violence. Schwartzbach said that even if someone threatens you and said they're going to beat you up or kill you, the law doesn't give you the right to slug them.
In 1839, after the death of a congressman, dueling was outlawed in Washington, D.C. A constitutional amendment was even proposed for the federal constitution to outlaw dueling. Some US states' constitutions, such as West Virginia's, contain explicit prohibitions on dueling to this day.

For one, in a number of US states, mutual combat is recognised by law. Two participants can engage in a fair fight as long as they don't hurt bystanders or damage property, often under the watchful eyes of cops themselves!
