Grubicide 

The brutal and gory (but yet extremely satisfying) act of a human killing any of the Locust horde in the Gears of War Universe.

Murder, for example by Curb Stomp, Longshot Headshot, Lancer-saw Shredding and Boomshot Oblivion, are just a small sample of hilarious types of Grubicide.

Grubicide is certainly not a punishable act under human criminal law, in fact, it is very much encouraged as the chance of extinction of the human race would be very much likely without it.

Dom Santiago: Marcus, man... I miss my sweet darling Maria! (cries like a lil' b*tch)

Marcus Fenix: For f*ck's sake Dom, stop being a whiny p*ssy! These Locust pr*cks are coming toward us! It's time commit some serious Mass Grubicide!

Grouponcide 

A business decides to offer too good a deal without the right limits or caps and goes broke due to a Groupon promotion.

Company offer $100 worth of merchandise for $30 and has to pay Groupon $15 of the $30 leaving them just $15 for a $100 worth of product. Now even if they were operating at a 60% mark-up the product still costs the company $40 and they only get $15. If they sold 1,000 Groupons , then they would be in the hole for $25,000, Grouponcide!

Grumpicide 

Grumpicide is a cover of the popular song “sad” by xxxTentacion that gained traction in the late 2010’s. The exact meaning is unknown of the word, but it likely has to do with an older lad by the name of Grump who is sexy.

“Grumpicide if you’re ever tryna hump Grump”
