prawn

An undesirable ex-girlfriend, ex-shag-buddy, ex-one-nite-stand, ex-partner. prawns cause an uncertain uneasiness with the new spouse even though there is no need as the ex has been discarded for reasons such as lack of spine, thick skinned harshness, lack of personal hygiene, creepy arms or legs ... ETC.

GF - i know ...
