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.

Play ball

In a relationship in which one partner is polyamorous, the act of the monogamous partner allowing the poly partner to occasionally have sexual relations with other partners. Similar to a “hall pass,” it shows respect, trust, and mutual understanding between the partners. Those who refuse to play ball are frankly immature, possessive, controlling, and often abusive to their partners.

I thought I’d never get to hook up with Bella, but luckily her boyfriend decided to play ball. He’s such a cool and understanding guy.

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.
