clapptoid

An complete fumbling idoit. Has absolutely no idea what they are doing but thinks they do. Just the most moronic human you know but they are so kind you just feel bad for them. Generally used on friends as a sort of kind abuse where you don't actually mean it really.

Your friend made a silly mistake on a maths question and looks at you confused as he/she didn't spot where they the mistake.
You reply 'clapptoid' and then promptly help them spot the issue
