fartass 

Just a random insult. Combining "Fart" and "Ass." Or accusing one of passing too much anal gas. Not an insult to be taken to heart, however. Fun times.

"Hey, John, how about you stop farting, you fartass."

Fatass Jonny 

"Fatass Jonny" is a term created on December of 27th, in 2020. First ever footage of such term used was documented in the video titled, "Fat ass Johnny (CSGO Moment)" uploaded by the channel, "Mrbailey channel". The term is frequently used in the CS:GO community. It is used to call someone who spent, or currently spends, money on the CS:GO game starting from when the game became free in 2018.

Clarifications;
An individual cannot be called a "Fatass Jonny" if they sold something on the Steam market and later on bought something in CS:GO.
An individual can be called a "Fatass Jonny" if they took money out of their wallet to buy something in CS:GO.
An individual cannot be called a "Fatass Jonny" if they took money out of their wallet to buy a Steam gift card and then purchase something in CS:GO.
An individual can be called a "Fatass Jonny" if they bought an item in CS:GO that was planned to make profit from, but failed to do so.

Danny spent $20 on a CS:GO skin out of his own wallet, he has now become a Fatass Jonny.

Lev is not a Fatass Jonny because he sold his skin for $20 when originally he bought it for $15, and therefore made profit.
