Me: No she was too moudly, she started getting sick everywhere!

Friend: Are we heading to a pub tonight?
Underage Friend: No fuck that we'll go on the nac and get mouldy on the lush instead!

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.

The state of ones penis after a heavy bout of profuse masturbation.

The times when you need to wank but simply cannot climax. You are in the state of perpetual soft-on. Excessive masturbation can lead to a grimy, chapped and bruised penis. Once in this state it is said to resemble an out of date raw pork sausage.

Wanking more than 10 times a day can almost certainly lead to a mouldy sausage.
