literal definition is someone who takes credit for someone elseâs fart
Also someone who steals your thunder or someone who takes credit for someone elseâs work
I worked so hard on that project and Vincent stole all the credit even though he hardly did anything. He never even mentioned my name. Heâs such a fartnapper!
I canât go to the beach this weekend because the salon screwed up and gave me a trump. Now Iâm too embarrassed to be seen in public!
