Black Ball Play 

When you play basketball with exclusively black balls. This is unlike the famous story of Rosa Parks.

I only do black ball play, none of that orange ball play shit.

If there's grass on the field, play ball

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.

play ball

1. to be a sport
2. to go along and do what you are supposed to

From Reservoir Dogs :

(talking about tipping and the fact that tips are taxed)

Mr Pink: (...) Look, if you show me a piece of paper that says the government shouldn't do that, I'll sign it, put it to a vote, I'll vote for it, but what I won't do is play ball. (...)

Meaning he will not do like everyone and start tipping waitresses.

if there's grass on the field play ball 

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.

You play ball like a girl 

The worst insult any man can bestow upon another man. The slight utterance of this word will leave another man dead where he stands.

Only use this if the roast sesh you’re having has escalated too far

Guy 1: “you bob for Apples in the toilet, and you like it”

Guy 2: “you play ball like a girl!”

Guy 1: *collapses*
