The act of taking a dump while straddling the toilet in an unlocked stall, relentlessly jerking off like you've been in a desert for two months surrounded by dudes. Climax not required. Exhibitionism desired. Shame optional. Spit for lube...the dirtier the better.
J-Bird walked into the bathroom...and caught this jerkoff was giving himself The Boykin! The kid just made direct eye contact, Boykined harder, screamed "Ggghhhhhhhhhhhhgggg, Ghhhhhh, Ghhhhhhhhhhhhggggg" then denied the confrontation.
