the "BHJ": A sexual act given to someone using the hand; however, using the hand in an upside-down U shape and smacking the head and shaft of the penis, quite unlike the typical jerk off formation of the hand. Thus, the term "bad" hand job arises after a poor misinformed girl performs this act onto a fellow male companion
Megan: I want to give you a hand job.
Todd: OK, jerk me off baby.
Megan proceeds to give a BHJ (bad hand job) to Todd failing to stimulate him
