Cheeseblock
This is were a person pulls a face that resembles a block of cheese to form an excellent jaw and expression structure, The facial expression will come across as quite down-syndrome-like. It can be used for humorous purposes to ruin pictures and in everyday life.

Also if you successfully Cheeseblock somebody for 30 seconds without them recognising they will owe you a drink

If you vibrate your head while performing the Cheeseblock results may improve in freaking someone out
