A male who is extremely good in bed, usually because of having an enormous dick.
Yesterday I found out that my man is definitely a j rock!
A man with unrivaled sexual prowess. he has huge yet defined muscles due to his copious sexual activity and is known to only copulate with the finest of females (models, actresses, singers etc). Some men are intimidated or feel nervous around women they find sexually attractive. not him.
Hot Bitch 1: Woah look how sexy that guy is over there. I know his jeans aren't particularly tight-fitting but I swear I can see the outline of his thick, meaty cock.
Hot Bitch 2: Yeah I know, check out how muscular, yet defined he is too. He's left me with a wet, quivering quim.
Hot Bitch 1 & 2: It must be J Rock!
