one time i was smoking with my friends, over here at that place. we were smokin a blunt. so by the time we finish, i see my friends hat. it said "SB" on it. i don't know what it stands for. so when i realize that we are almost done with the blunt, i remembered my other friend rolled another blunt before we smoked. so i looked at my friend's hat that said "SB", then started laughing. i pointed at his head and said...
"hahahahahahahahahahahaha..... your hat says "SB". hat said "so?" and i said "that means second blunt."
