When you go to bed with a stunning blonde and wake up next to fat Bob's granny. It is then that it dawns on you that when purchasing your beer goggles you REALLY should have gone to specsavers.
Guy1: Dang, i swear she at least had legs when we was in the club
Guy2: Yeah....You should have gone to Specsavers.....
A bloodyannoying advert on British Television and if somebody says anything to do with they can't see something, you'll get the classic response of "Should have gone to Specsavers"
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
