hashtastrophe 

an event caused by a poorly rolled hash joint exploding at an inopportune time which results in burning hash embers falling on the felt of your poker table causing great damage, followed by laughter.

Poker player one passed the poorly rolled hash joint to poker player two and the motion caused a hashtastrophe!
Wow, this table looks like it as survived a few hashtastrophe's.
Roll that better, so we avoid a hashtastrophe.

A complete hair disaster.

I've dyed my hair 18 times now and it still looks awful! What a hairtastrophe!!!

hatastrophe

Walking into a store (Asda, today) and impulse buying a stylish beanie without trying it on (in case it made me look a dick) only to get outside, try it on in the car and realise that I looked a dick, but £5 lighter.

I had a hatastrophe at the Wal Marts today; i could have spent that fiver on scratch cards and not looked such a dick.

Cashtastrophe 

When you check your bank balance and realise you spent more money than intended.

I just bought three things on afterpay and now I’m too broke to buy dinner. What a cashtastrophe!
