Surprise anal sex that is done without consent by the receiving end during an otherwise consensual sexual encounter. Refers mainly to cases in which the receiver is uncomfortable with the situation but doesn't necessarily do anything to stop it.
Me and that guy hooked up. It was weird...it was good at first but then he just gave me The Vegas Surprise out of nowhere! I just thought it was kind of rude.
