Mackerting is the art of wearing a shirt one size too small. While more often then not this shirt will be collarless and will feature a v-shaped neck, Mackerting is not limited to v-necks. It is possible to Mackert in any type of shirt including, but not limited to: t-shirts, polos, button-downs, soccer shirts, basketball jerseys, and henleys.

A person who is full of crap, lazy, and mocks everything by using irony, sarcasm, manipulation and/or outright lies as a way of life.
Student 1: Tom's a mockerizer!
Student 2: Why, what did he do this time?

Student 2: You hit the nail on the head! He doesn't even have a dog! Definitely a freakin mockerizer!
A giant metallic robot strangely obsessed with saying 'Monkertron' in its metallic robot voice, and hiding and singing in the undergrowth scaring the Lavatory Shrews. The Monkertron is clearly an early (failed) experiment in AI as it often mis-quotes items in its memory and can often trip when trying to mult-task and say 'Lloyds' while walking. A pungent odour often surrounds Monkertron and some external staining is often evident especially around the omelette region.
Winda - Listen, you smell something?
Toilets - Ohyeh, it's that stinking Monkertron
