emo grin

a small grin an emo gets while seeing another person in a great deal of emotional or physical pain which they find extremely funny but cannot laugh because laughing is very un-emo, so they settle with a small grin.

someone falls and breaks their arm before a very important event that involves them using that arm. An emo would see this and develop a smirk. (emo grin)

GRIN

an acronym for the set of technologies: genetic, robotic, information & nanotech.

the convergence of theses technologies into a single technology.

investing in GRIN stocks is a sure thing right now.

our children will need access to grintech if they are to compete in a global economy.

GRIN technologies are the modern day 4-horseman of the Apocalypse.

grinding

In skateboarding or other roller sports, this term basically means doing an ollie (or jump) up onto the edge of objects like tables, rails, fun boxes, etc. with a skateboard and grinding it along the surface until you pop off of it back onto another surface or back onto the ground.

You can catch me grinding pools all day.

50-50 grinding is what I am best at.
