Similar to a rookie mistake but broader in scope and consequence.
Saying he could have a party that weekend was a major wookie mistake.

Get the wookie mistake mug.
Getting so drunk the night before that you wake up the next day to a fat hairy (ocasionally mexican) "female" laying next to you

Also, marrying and/or allowing your best friends to marry and cohabitate with a large, hairy hemanbitch, that is always busting out of clothes 3 sizes too small, while sitting on the couch eating ice cream and asking their counterpart to bring it back and forth from the freezer because she may burn calories on the way that she must have to maintain her wookie figure.
"Man, those jaeger bombs tore me up so bad I made like 3 wookie mistakes in a week..."

"I am a sad panda...I let my friend make a wookie mistake, and now he is lost in the jowls of that nasty hemanbitch."
