The unstopable urge to confuse people on purpose.
Example 1:

2 kids working on a science project:-

Dawn:So how do we find the molecular structure of the atom?

Jerry: by flipping to page 86 and completing the lesson about molecular shapes and how it contributes to air pollution.

Dawn: WHAA..??!

Jerry: nothing, I like tuna.

Dawn: Quit pulling a mashie and concentrate with me!!

Example 2:

Stop mashying around your confusing the shit outta me!

Example 3:

I'd love to mashie him right now, look now guillable he looks!
