Puñetito is the nickname given to a kid that was caught watching porn on a computer in a computer lab in the Universidad de Puerto Rico Recinto de Bayamon. He was made infamous all across the universities of Puerto Rico and the even in the USA because of the video. Remember that this all happened a few days after they caught the singer Elvis Crespo masturbating in an airplane. His name is now a synonym for masturbation, watching porn or both.
Dude I just pulled a puñetito the other day.

Son of a bitch, I was doing a puñetito in the computer lab the other day and someone filmed me.
