Get the Custis mug.
Young kid who ruins the scene by seeking street cred. He gathers this by taking credit for others actions or claims to know everyone of value. Often provides links to other people's work and acts as though he has done it himself.

Get the Custy mug.
(In the terms of Super Smash Bros. Ultimate) A custom combo that is extremely cool looking, flashy, and unique. They are generally not true (as Cogger has pulled them off) but nonetheless are still very impressive. The term "custy" was originally derived from the "Underdogs" Super Smash Bros. channel, from the video titled "TOP 10 CUSTY COMBOS", appearing within the first 39 seconds, spoken by Jackson "Cogger" Cogger.
