Verb - to crumble.
The disappointing act of giving up on one's intentions, usually at the very last minute. This usually involves peer pressure or just a total lack of backbone.

Adjective - to describe a person who is likely to crumble often. e.g. 'That guy is a right crumble'.

Sometimes this adjective becomes a nickname as such, but this is only ever used when someone is a notorious crumble.

Nick: "You coming out in 2 weeks, Don?"
Rose: "Yeah, sure"

*2 minutes to night out*
Nick: "What time do you wanna head off, Don?"
Rose: "Not going, sorry......"

----- (This can work the opposite way round too) ------

Nock: "Ermm..."
Juan: "Mate, you propa crumbled!"
