To get trottered is to wake up one morning with someone you barely know and have no idea how you got there. This is usually followed by intense feelings of shame. This is especially relevant when both participants are in this state.
The only legitimate time to use the memory card
Guy 1: Dude I woke up next to this random chick this morning and she had no idea who I was.
Guy 2: I saw you in the club, you two totally got trottered last night.
