1 definition by OMJB85

An individual, typically a college aged male, that spends his weekends crashing parties in order to shoot game at drunk and desperate women. Someone engaged in the act is typically described as perpin or straight perpin. A typical perpetrator travels in a party of no less then 2 other perps.
The awkward freshman hitting on Betty was clearly a perpetrator and was quickly removed from the party.
