Putach is derived by applying ebonics to the spanish word "puta," meaning bitch or whore (see Puta). This would be equivalent to saying "Biotch" in English. Putach is often used in a comedically pseudo-insulting manner such that it allows one to both call someone a bitch and make them laugh about it at the same time.
1. Your girlfriend always pushes you around, grow some balls and quit being such a putach.
2. (Following an very competitive game of any type) YEAH!! I just stomped your ass, putach!
