debag

To remove (something) from a bag.

[…] when such bags are used for organic materials destined to be composted, the plastics create nothing but problems. Materials must be debagged before composting […]

To pull down the trousers of a person quickly by surprise, as a prank.

I don’t want to be debagged! Don’t you play the giddy ox with me!

To perform blepharoplasty; to remove eyebags.
