When sketching out of boredom, what do you usually end up drawing?

buttholes , but some people say they look like eyes.

Just gothy anime looking people doing normal stuff like drinking tea, trying on a hat, laughing, etc. They're mostly women since I find them much easier to draw. They're also usually wearing something skimpy since that's easy too.

Portraits of people that don't actually exist

I'm surprised no one said "dicks", since that's the most common thing I see scrawled on bathroom walls, picnic benches, textbooks, and drunk guys' foreheads.

Cartoons!

Weird creatures I make up.

I draw derp faces and occasionally slightly desturbing eyes, people and stuff

Hands in weird positions/ holding different objects

Noses

maps of places I know well.

Anime girls. They're easy to draw.

Eyes or random shapes. Sometimes girls running or just standing around.

a dick which then either turns into a smiley face or a cat or sometimes even a rocket ship.

Galleons/galleys/longboats, knights, abstract patterns and forms.

Trees

Liquid stuff like water or sticky goo.

Faces with the eyes gouged out

Squares and shit...

More rarely a tree, a river, and a guy playing ball.

Sheep

Doodles mostly of a guy with T shaped eyes and a half smile. Then I make random patterns until they end up becoming something else.

I want to start a comic and occasionally draw a couple dudes talking about what's on my mind, but those tend to boil down to one criticizing my avatar for failing to draw him consistently, prompting him to erase the other's head out of frustration.

Unless vector art on the computer counts, I'll spend hours designing a tile wallpaper for no reason. I've got a couple that I'm kinda proud of.

Mountains and birds

Math formulas. Arabic or Hindi letters.

Letters

Slug cats.

Eyes stars abstract shapes letters

I dunno, it's been so long. I have done some coloring lately though.
