that's a good one. It seems strange to hear full grown adults (and by "full grown" I mean people who are in their mid to late 20's) saying "hells yeah". It's grating to hear someone say it, and it's even worse to see someone type it. It just comes off to me as someone who doesn't want to admit they're old. Quit saying it, you look immature.
Git-R-Done. So Annoying Another one has to deal with my register at work, people are like "Oh are you Open?" Nah, I'm just standing here because that's what I like to do in my free time.
