Coinflip player

Two meanings:

1. Someone whose playstyle in a competitive video game is feast or famine, in that they will hard carry games but also hard lose games by themselves.

2. Someone who has little to no impact on the outcome of a game so whether they win or lose is entirely dependent on how the enemy team and their team play irrespective of the player in question, hence the term coinflip - the player essentially flips a coin to win since either their team or the enemy team is better and they have no control over that.

1. John is such a coinflip player. He either goes 5/0 at 5 minutes into the game and carries or goes 0/3 and afks.

2. Bob is such a coinflip player. He just spam queues up games all day with a 50% winrate and either farms just to loses anyway or his team carries him.

Maldlet

A portmanteau of malding and brainlet i.e, someone who is both mald or malding and a brainlet.

Talha: wtf my hairline has receded even further back since thursday you've gotta be fucking kidding me man!
John: Don't worry mate, it's not that bad being a maldlet.

brTT

A former Brazilian league of legends professional player who mained the ADC role.

Most well known for being better than the North American flash-saving ADC 'Doublelift' resulting in the copypasta 'brTT > Doubelift', after the Season 5 League of Legends World Championship in which the two faced off, with the American losing.

Even seven years later, Doublelift still malds at viewers who come into his twitch stream just to say 'brTT > Doublelift'.
