A game you play with people when you are driving. As soon as a person see's a car with three headlights, the person yells three play, and hits the roof with his hand three times. The last person who hits the roof is a mcfaggelwaggel, and has to take off one article of clothing.
Gabe: *hits roof* Three Play!
Riley: *hits roof* Three Play!
Zach: *hits roof* Three Play!
Nathan: *cries and takes off one article of clothing/accessory*
A term basically saying that it's alright to at least be attracted to a person as long as they've gone past puberty. Obviously "grass" refers to their "bush" or pubic hair. Would typically be applied to, for instance, a girl maybe 13 years old and up. Can often be used in reference to actual sex (intercourse) but not necessarily.
Man#1: What's the youngest chick you would ever be into at your age? I mean what do you think is "okay" to fantasize about?
Man#2: Hey man. Like my coach always said: if there's grass on the field, it's time to play ball.
when a woman won't let you have sex with her because she is on her period or when you don't wantperiod blood all over your penis, you have anal sex instead.
If an underage girl has reached puberty, she may be considered appropriate for sexual activity. The reference to "grass on the field" is a metaphor for pubic hair, meaning that any girl who has reached sexual maturity, may be an appropriate sex partner.
An expression used before or after one takes a piss, meaning that if it takes more than three shakes to get rid of the excess pee it can be considered masturbation.
