Oh man, my buddy giggledicked me so hard the other day.
Oh yeah? How?
Theres a stop on the bus route called "Downsview" and he said "I didn't know down syndrome affected your eyes"
The giggledick is the act of 5 or more penised individuals forming a circle with their penises pointing toward the middle. Each participant then laughs simultaneously until one ejaculates, which usually invokes more laughter, thus creating a snowball effect.
