trash tier
This is the common name for someone who plays a game or performs any repeated action for an extended period of time but never shows any sign of improvement or actual skill in the game or action. Typically this person still assumes that they have speaking authority in this topic(and any other topic for that matter) while possessing no evidence of intelligent life. You should always avoid a person like this as listening to them can result in loss of brain cells and thoughts of suicide.
The trash tier employee likes to brag about being bronze in League instead of actually working.
