The final moss of a series of mosses, where a moss is when a potential victory or spotlight is stolen or thwarted, or in sports like
basketball and
football where someone steals or catches a pass that was intended for someone else.
A missmoss in
general context is the last laugh of a mossing battle of any kind.
Football quarterback: (hail maries) "Catch!!"
Football player #1: (jumps for catch) "I got it-- O_O"
Football player #2: (steals catch in
mid-
air) "XP Mossed! Wait wha--"
Football player #3: (steals moss in
mid-air) "Hahahahaha! You just got-- :O"
Football player #4: (steals #3's moss in
mid-air) "ROFL. Get rekt-- XO"
Football player #5: (steals #4's moss in
mid-air) "LMFAO. SIT BOI-- O_________O"
This goes on for a bit....
Football player: (catches previous moss and lands) "LMAO. Missmoss!"
Football quarterback: "Lol XD"
