A tall, built, and dirty individual who's bad personal traits far exceed the good.

A Imum's worst trait is thinking they are "entitled to something" often asking for several favors in a single day.

Don't expect anything in return from an Imum, they are very self centered and only care about themselves.

A Imum can also be used to describe someone with very poor personal hygiene skills.

A Imum will cause an argument at every opportunity and put other people down in a pathetic attempt to make himself/herself feel better.
Dude don't be such an Imum and ask someone else to pick up!

That person has such nasty splotchy white teeth, totally an Imum!
