under hater 

A jealous coward that works against you either by talking shit when you're not around or taking actions to sabotage your efforts. This person is usually a pretty big biter

Confronting this person usually results in whimpering denials. This person's actions against you usually end pathetically. Beware it is very common for this person to know you well enough to recognize your talent, intelligence and creativity.

underwater camel 

Similar in nature to that of an overwater camel, however this vertebrate skims the ocean floor in search of underwater grass. It stores water in it's humps in order to breathe for longer periods of time. The underwater camel is native to Ottawa, and generally live alone because of the cold weather, however occasionally they may mate with a backwards deer to create an underwater deer camel.
