When you talk too much, about too much, that may may or may not be related to the conversation in progress. It must offensive, always. It is the thin line between tasteless, and genius. However, one of the strongest points of pulling a "Coatsy" will be to use elaborate free association to legitimize the already disenfranchised diatribe in order to justify the relentless word storm.

this is a "coatsy" in progress.

Get the Coatsy mug.
Coatsy :annoying, a douche, your best friend and worst enemy, obnoxious but friendly enough to not remove him from your life, it maybe in fact you can't physically avoid him as one is always around.

One to frequently ask for lifts and gobble goods from your Fridge at all hours and give nothing in return but on special occasions may buy you a meal if you look hungry.
Coatsy washes his hands in the punch bowl because he is too superior to wash them in a sink like his commoner friends.
