The fine art of taking a Dump in someone's handbag without them knowing. A great way to impress your dissatisfaction with someone for leaving their handbag somewhere accessible. Not advisable on first dates or when taking elderly relatives to dinner.
Handbagging is often preformed on a night out when a really annoying girl (or guy (doesn't even have to be annoying (just has to have a handbag))) and you get the opportunity to grab a handbag on the way to the bathroom or anywhere else you are comfortable doing 'the deed'. Not being caught is usually advisable.
Also good for a competitive game with mates seeing who can get the most or the best bag!
The bizarre series of hand gestures that many of our less effectivepoliticians have been trained to perform, in order to distract attention from the vacuity of what they are actually saying.
