The Red Card

When a girl is on her period and you are having sex with her and blood comes out in one big clump and you pick it up and raise it above your head and make her leave your apartment

Dude, I was fucking this hot chick on her period and I had to give her the red card.

Eat the red card 

When an individual is completely refusing to follow the rules or acting in a completely irresponsible manner, usually with no respect to the outcome.

Derived from a Jordan Holmes story of a soccer playing committing an offense, receiving a yellow card, eating said card, then receiving a red card for eating the yellow card, and finally eating the red card while being ejected from the game.

Lawyer 1: "Oh god my client is refusing to hand evidence over to the state, he is destroying any chance of winning this case and I might be sanctioned over this."
Lawyer 2: "Your client is really trying to eat the red card on this one."

REDcard 

The ultimate goal of Target's disillusioned LODs and GSTLs who whip their cashiers with spiked belts at every prompt to try to enforce their will against unsuspecting customers.

Usually the result of a life of shit, failure (i.e. dropping out of college, high school, getting fired out of a more prestigious position), and overall the ultimate fear of losing their job even though they're already working under shitty conditions at little over minimum wage.

Victims are usually high-school students with potential or mentally retarded and morbidly obese individuals that can't find a job anywhere else.

I just started working at Target a week ago, and this nasty bitch with crooked teeth and a terrible lisp told me that if I don't get redcards, she'll murder me and rape my family.
That hurt my feelings, (so I yelled 'This is SPARTA' and roundhouse kicked the b*tch and got the fuck out of there).
