n. A fatty boom batty is packing a fat lip of dip and being fratastic. Throwing in a fatty boom batty is a past-time assosciated with playing video games, watching tv, and in the scummiest cases...making out with a girl. Fatty boom battys are best when used with skoal mint, skoal straight, and bandits. The ultimate fatty boom batty is also known as the Civil War, preferrably with a full sample tin of skoal minter on the bottom and mint bandits on the upper. I t is not a fatty boom batty if you dip while beating off, then it is just dirty and scummy and for pussies not man enough to get on bitches with a true fatty boom batty in. If u want to be really fratty, then call it a fratty boom batty and pack 8-10 lippers a day.
