person who is totally full of it

A Bloomer is someone with a bright outlook on life who is optimistic in nature. Bloomer's frolic in every opportunity to be happy and try to make the most out of life.

Poop flinger is a monkey, or sometimes monkey-like people who fling poop. The poop vary from large smelly ones of their own, to small not-smelly ones from their friends. THey're not in danger, they own the jungle. All other niamls are terrified of the poop flinger. Their leader is Mertek.

Someone who knows only how to fling insults and vulgar language in an argument (much like a monkey flings poop) rather than give their opinion in an intelligent, rational manner.
