This one sounds like it would be extremely fun!
Hit your hand/head/limb (I'm a hand person personally, my head is
valuable) on the keyboard to get a load of random letters. So
like...erhm...
ilhp
and then we have to make an acronym
(next person does that). Like:
I Love Half Prince
and then
get another acronym.
It can make as much or as little sense as
you want!
Begin!
