A word used to describe a female who has previously been twanged or is due to be twanged (see 'twanged').
Not to be confused with the alternative meaning which simply means a girl is fuckable.
Twanged / twanging / Twangage - The art of discretely unclipping a females bra with the click of your finger and thumb in one swift move to create a look of panic on the recipient of the twang. This tends to work best on an attractive work colleague at a Christmas parties etc.
'You're so twangable', 'she's twangable', 'I'd love to twang that', 'seriously twangable' etc.
The weird feeling you get when you are expecting to experience a certain thing, but experience something else instead.
For example.. when you take a drink, and you expect it to be milk but it turns out to be apple juice.
Or.. when you are climbing stairs, and you expect there to be one more step than there actually is.
I had a twangle when I sat down there, the seat was muchlower than I thought it was going to be!
