A Grech is a derogatory term for a fellow human being, and spends most of his time in a cardboard box with little food. It is considered by several to be one of the harshest insults in the english language.

A really, really, ridiculusly unhealthy fat person. It was named after one of the fattest humans currently known to exist. His weight is currently unknown because no scales are strong enough to hold his fatness.
