There are four bases in a relationship

First base
Second base
Third base
and finally
the Home Plate

First is making out
second is making out with the tongue.
third is touching
and fourth is sex

There are times where there are accidents like rape and underage sex which is considered rape regardless of age. This is when the Bill Cosby Card gets played. Normally it is the man who plays it.

Once the card is played the male is in prison for a matter of 3-10 years for rape.

Don't say I didn't warn you. You already played the card. You're now a registered sex offender.
Troy: I heard Trevor played the Bill Cosby Card, Owen.
Owen: He did WHAT?
Troy: He pulled the Bill Cosby Card!
Owen: Did I hear that right?
Troy: Yes. Trevor boned Amanda just as they started dating and she filed a police report about a rape!
