The opposite of self first. Self last requires your buddies to stick with you to avoid awkward situations that could arise from a person of the opposite sex wanting something you do not want anything to do with.
Your friend really wants to make out with you and you know he/she is planning on making a move but you want to avoid it. Therefore you call "self last" to your crew and they are forced to hang with you so no moves can be made.
