Arpad Elo developed the self-named elo rating system, a system designed originally to fairly calculate the overall rankings of chess players. Elo has also seen exposure in different sports and games, branching off to areas like Football, Scrabble, or Backgammon, and video games such as Guild Wars, Starcraft 2, and League of Legends.

In a roughly abbreviated explanation, players under the elo system are placed at a specifically middle rating, say 1200 in League of Legends. With subsequent games, players can increase their score from victories or decrease their score from losses. The fine tuning of points earned when winning or losing a game are usually made separately for each type of game, as different mechanics are involved.
A: Man, I've been losing so many games, my elo's almost dropped to three digits!

B: That sucks, there's not much you can do besides get better.

Elo is a traveler at heart. She the most caring and loving soul you will ever met. She loves the ocean and painting. She very artistic.

Her heart will be grounded by her family and her love for her kids.

But her soul will dance at the ocean for ever.

If you met a Elo never let her go or you will dream of her forever.
Elo the dancing Gypsy queen

Oh there’s Elo swimming in the ocean

Elo’s got the biggest heart

Short for elephant dung. The term elo means that something smells like elephant dung or simply feces. One could use 'elo' to refer to a horrible smell of shit, or actual shit.
Man that bathroom really smells like ELO.
