a girl friend who only wants to give you painful hand jobs and tell you about her old boyfriends. ("B.F." for best friend. "Skinner" for a hand job. B.F. Skinner was a famous behavioral psychologist of the 20th century)
My first girl friend was a real B.F. Skinner. All she ever did was yank on my cock and tell me about the guy she lost her virginity to.
This acronym means Believe Enemies Never Zone In.Meaning that there enemies are never allowed to get any momentum against them.For example if you are playing James Harden in basketball and he gets in the zone or zones in he will beat in a heart beat but,if you never allow him to zone in your have a better chance of winning.
