reindeer chocolate
When you shit in a kid's stocking.
Instead of giving the naughty kids coal, Santa now gives them reindeer chocolate
Chocolate Reindeer
When a guy, possibly drunk and dressed as Santa, gives his partner one up the arse from behind, whilst grabbing her hair ( preferably pigtailed for full giddy up effect ) and saying Ho Ho Ho, Merry Christmas!
Boast; The missus was so pissed last night, she let me ride the Chocolate Reindeer!
