I've seen it recommended on MN as the perfect retort to use on a CF. I've just seen it used on a thread. But it's rubbish!
Who's been on glue since the 80s? If someone used this insult on me, I'd think they'd learnt English from watching Grange Hill. And then I'd just say, "No," with a tinkly head-tilt. It's hardly the type of dazzling put-down that leaves you gasping for breath.
AIBU?
