Someone fine, who turns you on all the time. Sweet as sugar, hot as hell, they really make your penis swell. Sleek and sexy as they row, and then good God, you've blown your load!
She is a constant source of arousal, just one look at her will send your pulse racing and the blood pumping (especially to the area which needs it the most. yes fellas, you're bound to have to cover yourself when this girl walks by)
She is a friend to all, but the leprachauns have a special connection with her. They tell her to burn things. She was the bow of our boat; the first to die in a collision with stupid bloody Walford *die evil men* and has been promoted to stroke seat, where she arouses us all with her fine sexy ass. She is a slave to the simpsons, no one day is complete with out her mandatory Simpsons' quote. whether it be in the showers in the moring, (you'll have to speak up, I'm wearing a towell!) or a random simpson song break out, which can happen any time! We all love her, and want to bear her children. I shotgun her as mine! We have some unfinished business to take care of! *Gets naked*

ISY
stands for "It's Senior Year". ISY can be used interchangeably with "YOLO"; it is used to justify otherwise questionable behavior during the final year of high school or college.
Tony- "I hooked up with another freshman last night. Is that bad?"
Joe- "Not at all man, ISY."
