When a fat ugly chick gives you a blow job.

It's like eating a whole pineapple without peeling it.

Yeah, it feels horrible.
Example 1: "Man yesterday I got so fucking drunk I got a Grenade Blowjob, now ma junk hurts..."

Example 2: "If my friends ever found out I got a Grenade Blowjob, they wouldn't talk to me anymore. LOL"
