It's the worst fucking thing for an artist to ever encounter. It's when you run out of ideas to draw things off, and temporarily loose all motivation to do anything art related.
You'll often see artists on deviantART not post anything for a while, and then come back complaining of an art block.

A few weeks ago, no one had “cheugy” in their vocabulary . Now everything is saturated with the word. It’s in our heads. It’s in our homes. Everyone is asking: “Am I cheugy? Am I a basic ass bitch? Am I GUILTY of being cheugy?”

The proliferation of cheugy in the mainstream discourse can only be attributed to one source: mental terror. It’s an orchestrated psychological trap to make you question your tastes and interests in the eyes of others.

You are not a cheug. YOU’RE PERFECT!!!!

It is very suspicious that the cheugy mascot is a Minion, a literal cyclops, a deformed
yellow panopticon in overalls ... do not let the all-seeing eye to control you. Be vigilant. Resist cheugy psyops.

When an artist doesn't know what to draw and just lies on their bed watching youtube like an idiot.
Or just straight up suffering

IT FUCKING HURTS LIKE HELL

When an artist, may it be anime or not, finds his or herself at a lack of ideas.

A FUCKING BAD THING THAT HAS HAPPENED TO ALL ARTISTS! I FUCKING HATE YOU ART BLOCK!
