mwould 

Mwould is a much better word then the regular would and can replace the regular would in any sentence.
It is mostly used as a reply when you at least expect it, people that have not heard of "mwould" are often considered racist or stupid.

Person 1 or you: are u happy now?
You or person 2: no, why mwould I?

Mouldy monday 

The Monday after a weekend amphetamine bender. Spending the day hot, moist and mostly stationary. Feeling like that crust that's been in the bread bin way longer than it should have been.

Man: I feel like shit...
Man2: Been on the phet again?
Man: Yep... Mouldy Monday as usual.

Jelly Mould 

1. A mould for Jelly (n.)

2. The yellowing, crusty stain found on the front of a pair of pants that have been left in the washing some time after having been defiled by gentleman juice.

Bridget Jones's sensible pants were the only ones left untainted by jelly mould.
