The contorting of the face in a gremlin like fashion; usually noted with squinting and/or closing of the eyes, widely opening the mouth, and sticking out one's tongue as far as possible with the intention of engaging in pseudo-sexual behaviours and/or exercising such desires. Drooling saliva from the mouth is optional. Gremlins are known for participating in such behaviour when excited, having a good time or about to pounce on an unsuspecting victim.
Check out Brian gremming over there! He must be thrilled he finally got that chick’s number!

Those girls couldn’t stop gremming as we took pictures of the male strippers giving them lap dances at Jenna’s birthday party.

Amanda revealed herself as a gremlin when someone tried to take a picture of her and she opened her grem-latch and stuck her tongue wide out in excitement.

Rubbish skateboarder. Popular in the UK back in the 70's..
Gremtec Coyote skateboards .. Cheap little plastic planks often seen tictacking along the flat until the grems riding them realise the reason they cant handle the half pipe yet is because 360's are not everything and a wider board is more stable..
And most of all, they are still grems!
