Bushknod

It’s a verb meaning to acknowledge someone talking to you with all the normal social cues such as bobbing your head in agreement and moaning “mhm” as if to understand what is being said but instead you are really so out of it from alcohol, or some other drug. (fyi, alcohol and nicotine are drugs)

I asked Andy if I could borrow his car last night at the party but he must have been bushknoding me because today he acted like we never had that convo!
