When a man has tight pants, it gives him moose knuckle (see definition). When he see's an attractive male/ female, he begins to get a chubby which increases the size of the moose knuckle giving it the appearence of being swollen.
Dude Blake was wearing some tight ass pants the other day and i was laughing at his moose knuckle. Then when he saw me, he started to get a chub and he got a serious case of swollen moose knuckle. What a faggot ass!
