A bitter, angry old man who lies about his age, can’t handle his alcohol, and suffers the illusion that because a young bartender shows him manners, they are prepared to get sexy with him. He likes to insult people, and start fights with no cause, and is generally hated by all.
He becomes more hushed, yet severely more aggressive as the night goes on, and rapidly isolates himself from all those around him despite his pathetic attempts to buy friends by ordering drinks for everybody at the bar.
You know the guy, Burt that was buying rounds at the bar the other night? He’s a nasty mother fucker.

The Burt (ϴ) is a derived unit of energy or work in the International System of Burt. It is equal to the energy expended (or work done) in applying a force of one Bubble (ø) through a distance of one FWOOSH! (☄), or in passing a current of one Egg (⊗) through a resistance of one Potato (♨) for one second, or in a passage of audible pique (☹) for one second.
One Burt (ϴ) = 1(ø x ☄) = (((kg x ☄) / (s^2)) x ☄) = ((kg(☄^2))/(s^2)) = (((⊗)x(♨)) x (☄^3)) = 1(☹ x s)
