Kevlar Neck Gaiter 

A metaphorical badge of loyalty usually referenced as an item of travel gear when visiting a good friend in a tight spot.

“I’m visiting my buddy in the Army next week but he’s stationed at a pretty wild post, you know, murders, kidnappings, war brides, that kind of thing; so, I’ll definitely be packing my Kevlar neck gaiter.”
“Jesus, where’s he stationed, Fallujah?”
“Nah, Fort Bragg.”

keplered

When the performance of something significantly degrades over time.

The names comes from the Nvidia Kepler GPU architecture (GeForce GTX 600&700 series), which was infamous for suffering severe and steadily bigger performance losses in games after its release.

This was caused by poor optimisation in Nvidia’s drivers after the release of the Maxwell architecture (GeForce GTX 900 series), as without shader optimisation the raw performance of Kepler cards fell off a cliff.

Person 1: Have you seen how slowly my computer’s been running recently?
Person 2: Yeah, it’s been Keplered

kevlar 

Material that is actually nylon streched very thin, which makes it much tougher. Used in everything from bullet-proof vests to gun stocks.

I only where about ten layers of kevlar. I hope that can stop a shotgun blast.
