Similar to the wideley known "Rim Job", however in this sweet sexual act, one must speak in a heavy Eastern England accent while swiftfully and forcefully lining another individual's cornhole. To successfully complete it, the person must yell "Rimmmaa!" in the heavy accent, and then give the Rim receiver a hug.
Last night me mate gave me The Rimmer, and by god I got more than I bargained for! The hug after was just somewhat awkward too...
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.
