Fucking clown is one of three things, a literal, fucking clown, or a clown you decided to add the word fucking infront of, or some bastard that pissed you off because he was being a jackass.
A fucking loser/ goof who is just a low life. Also probably touches little kids, and has done jail time. He also can't be taken seriously and owes people money
Reaction:
To Someone or Something that is so fucking redundant, words fail, minds melt & brain cells die! You can't even get up to punch someone hard in the face.
Action:
Fucking your partners anus with an over sized clown shoe.
