A sexual act that can be done by a threesome . A person would lay on their back, giving oral sex to a person kneeling over their heads. That person would be making out with another person also kneeling above the first persons genital region, having sex with the first person, thus making a triangle. The name for it originated from Texas, because of the crazy shit that the Texans do.
Even better! She brought in her friend Kerry and we did a mad Texas triangle!
