That one elderly woman in every area that has been around the block. Used, abused and has mastered the art of felatio.
when speaking about a woman like this tits, you refer to them as "BLTs" short for Big Lynn's Titties.

It’s an acronym standing for Can’t Remember A Fucking Thing. It’s usually used to describe embarrassment at being unable to remember someone (CRAFT moment); going onstage as the lead in the latest theatrical performance and your mind goes completely blank (CRAFT situation); the next morning after a night when you got pissed as a fart and woke up in bed cuddling a traffic cone and a string of fairy lights wound round your prick.
