When you walk around a corner, typically in a building with many people(school,bank,foodlion,popeyes chicken(lots of black people there)walmart, ect)and you head just so happens to fall right into a pair of unsuspecting breasts and jiggles around in them for about 5.7 seconds or longer.
Dude! I was walking out of third period and turned the corner too sharp and ran into this big boobed slut and had and Acidental Motorboat,it was amazing!
What da Tin Woodman had a number of when he was a regular flesh-and-bone dude, and which resulted in da subsequentmetallic status of his physique.
I don't have very good balance or hand-eye coordination, so to avoid axcidents, I always just stick to bow-saws when cutting firewood or otherwiseworking with trees.
