A BOB or battery operated boyfriend, is a device that is available for people with BUFs (butt ugly faces). It is shaped like the male penis and has many different size and modes it can be used on. Only difference between this and the real thing is that the BOB will never reject u like John from 3rd grade. Unless u 1, have a rabid vagina or 2 run out of batteries.

A game played with two or more people in which you take a small to medium sized industrial or car battery, and in increments starting typically at 1 inch high, drop it on your penis. Once each player has dropped the battery on their penis from 1 inch, the height is increased to 2 inches and so on. Players may opt out at any time, the last man standing is the winner.
