Riffs lah

Comes from Armagh/Tyrone in Ireland. Derived from "in the horrors here" and "horrifics here lah", which would be thrown about after a night of mass alcohol consumption

Then it turned into "riffs" and "lah", because fuck saying the full word "like".

"fuckin hell I was bananas last night. Hanging out of my hole here today. Pure riffs lah"
