Twin Sack

To get beat in a video football game (Madden or NCAA) by 21. The person losing by 21 gets a courtesy drive once the other player hits 21. This helps to move games along.

Tommy got twin sacked since he could not score on his courtesy drive, ending the game right there.

parasitic twin

In medical circles can refer to twin reversed arterial perfusion, or a subset of conjoint (siamese) twins. Two fetusii develop conjoined, but one (the parasite) does not fully develop and is wholly dependent on his host brother.

In team management refers to a redundant slacker who performs an identical, complete subset of the effort performed by a more capable worker.

a: we have the same job! we're like siamese twins!

b: nah, I do twice as much. you're a parasitic twin

Chip Twin

When one twin is clearly more attractive, cool, or likable than the other twin. After suffering through a lifetime of people asking where the "hotter" or "funnier" twin is, the less desirable twin inevitably forms a "chip" on his or her shoulder, thus making the chip twin even less enjoyable to be around.

1.

Party host: "Where is Andy? I love that guy. He's hilarious."

Chip twin: "Why is everyone always asking me where Andy is? How should I know? I don't know where he is all the time! I'm just as funny as he is!"

Party host: "Listen chip twin, you're not invited unless you are with Andy. Robin didn't go around trying to fight crime on his own."

2.

Guy at bar: "So how do you two know each other?"

Chip twin: "We're twins."

Guy: "No, seriously. How do you know each other?"

Chip twin: "We are twins."

Guy: "Come on. Seriously, how do you know each other?"

Chip twin: "You're an asshole."

*Twins walk away*

Guy: "What did I say?"

*Guy 2 walks up*

Guy 2: "Fucking chip twins, man."
