Someone who jumps at or scrapes into every single oppertunity that comes their way.
Someone who always goes to social gatherings, irregardless of whether they are friends with the host/people going or if the gathering will be dry as a desert. They will always be there.
Sam: Hey, is Sarah going to Matt's party tonight?
Tom: Yeah, she goes to everything. She's such an oppertunity whore!
The opportunity to do something new. This is especially applicable to people who are easily bored, or have low attention spans, or who have been working on something for way too long.
An oppertunity is a legendary weekend with the boys where the plans are loose, the alibis are looser, and the entertainment falls somewhere between “possibly illegal” and “we never speak of this again.”
Oppertunity:
A glorious chance to do something epic, usually involving the boys, bad ideas, and at least one thing you hope never shows up in your camera roll.
