look up any word, like plopping:
When you are at a restaurant and everyone is waiting to order you claim you are going to order something, when the waiter actually takes your order you choke under the pressure and order the same thing as the guy before you.
An Example of somebody Pulling-Musselman is below...

Steve:i think i will get the waffles

Jeff: I'm gonna get pancakes

Waiter: what could i get you guys?

Jeff: can i get the pancakes

Waiter: and for you?

Steve: uhhh can i get the pancakes, too

Jeff: Dude, you are totally Pulling a Musselman
