Having gone down on your girl, and she doesn't tell you she is on her period. You have probably consumed copious of alcohol and not realized your face is covered in blood. Its a bonus if you have a flat mate and when you walk out the room (with that cheeky grin that you just got laid) and your flat mate see's you.
(Flat mate) He/she would respond, "Ha ha, you've been poof guava'd".

Looking in the mirror, and seeing the clown makeup of the joker that you didn't see coming -"poof guava".
