Latencuck 

A delusional PC enthusiast that thinks they know better than engineers and constantly makes excuses for why they're bad at games. Uses terms like Mousefeel, DPC Latency, Residuals, CR1, EMI, Linpack, HyperThreading, IMLC, e.t.c. Thinks that using outdated and dysfunctional windows versions makes their PC run better. Shills decade old hardware because it has lower memory latency in a test yet runs everything else 1000x worse. Prone to be easily agitated and will likely call you unstable.

"That latencuck is always complaining about how much EMI he has and how his residuals don't match in linpack"
"Some latencuck told me to run linpack and now my cpu won't boot at stock settings"

latebuckler 

A person who buckles his/her seatbelt several minutes after getting into the car. In order to be a latebuckler, you must consistently late-buckle in an already moving vehicle.

If you weren't such a latebuckler, you wouldn't have gone through the windshield.
