When someone does something so absolutely stupid or ridiculous that you just have to ask them What The Fuck they are doing.
If I saw her doing something that stupid, I'd have no problem WTF'ing
WTFing stands for the times when you are confused about a situation and become angered by it and outwardly show your anger by throwing a fit
Sam and Holly were WTFing why the german final had so many things that they didn't understand
when you are too tired to function.. like waking up on monday and going to work,school,weddings, w/e
also can be used as wtfed
Jeff- dude i totally wtfed through that meeting
Ernest- i was wtfing through church today
