slubberdedavelewin 

When a troll or anyone named Dave posts an insult towards a specific group, something like a slobberdegullion, but it does nothing besides let everyone know that person knows less about the subject than those they attempt to troll

Dave: Mate you wouldn’t even know what a slobberdegullion is...
Anyone: just like you can’t spell Slubberdedavelewin
