fumbduck 

A fumb duck is a particularly stupid breed of dumbfuck. Its name comes from fucking up the insult 'you dumbfuck' where the insult obviously backfires.

Megan is a fumbduck.

The majority 99.999999999% of people who twitters also know as a dumb fuck.

I hate FumbDucks they are soulless idiots with no lives. I have yet to see a useful tweet or found a twit who can show me a useful tweet.
