Top definition
A phrase that if yelled at a party, justifies ANY otherwise taboo action or statement that precedes it.

Can be used in any situation.
You are blackout drunk and a kid tries to get you to vomit for your own good at a party. You pull a knife out on him and everybody freaks out and then you scream RAPTOR SURPRISE. Everybody then laughs and forgets about the previous action.

Great if used as a hashtag on twitter as well.
