Hypocrite

An idiot who does things that they tell others not to do and does it themselves because they're brain dead. The worst of these people are those insult the others who do it and then proceed to do the same thing themselves.

Sam (Hypocrite): Hey Jack! You better not do that thing you just did.

Jack: Ok

Sam : (Proceeds to do that thing)

Jack: Hey Sam are you stupid? You just did that thing you told me not to do.

Sam: Oh actually Jack, I'm stupid AND braindead!
