A weak person that always gets stepped on. All talk and no action. A non-vocal vocalist. Someone who will recieve a Dirty sanchez willingly and then complain to their peers about it later. Spineless fuck,supreme follower with alot of mouth. Coward of the highest order.

"Tom is such a jelly back at work." He always bitches about the job but never stands up for what he whines about!
That's why he oftens gets a dirty [brooke}.

"Yeah, but I didn't want to finish...so...."
"No way man... did you?"
"Yep, i did the unthinkable... I Jello Back'd her."

when a guy gives another guy rode dome but neither guy is gay. Keep in mind that both gentlemen are very proud and open about giving/receiving the blow job but they are "NOT GAY TRUST ME".

"Well they had a backroad jolly so i guess their not actually gay"
"Dammn Johnny and Clyde had a backroad jolly! Seems pretty cool man maybe we should have some casual bro to bro time"
