Page - last name.
Pretty Boy - 300lb manager where i used to work loved to call me this, cuz apparently i am a pretty boy.
Beefcake - from my rec soccer team in high school, started calling me this freshman year cuz i was the only one that actually ever worked out (mostly for track, but i guess a frosh benching 150 is pretty impressive).
Greaseymonkey - i actually have no idea where this name came from, people just started calling me it one day. if it came from a drunk story, it's nothing i remember.
