Square

A boring mainwashed sheep. No hobbies. No music taste. No dress sense. No sense of humour.

Frowns upon any type of drug use even though they'll have a drink and get drunk off a single pint.
Common sense in these beings appears to be null. They suck the life and fun out of the room upon entry.
They generally look down on others like they're gods gift to grace the earth and we should all be in awe of their presence even though they come across as a hostile, grumpy twat because they think they're better than everyone else.
Their family are the complete opposite and the parents wonder where they went wrong to spawn such a detached individual.

Probably washes themselves with fancy organic soap and eats vegan foods to the point of illness. They hate animals.

They are a lie to themselves and humanity.

major malfunction.

Hooman 2 - let's move away from it

There is no fun to be had

in its presence.
