Shouldn't college have a tattoo 101 class?

Not in the sense your examples describe. That’s silly… If you are planning on getting a tattoo, hopefully your tattoo arist can give you the basic information one would need. Most are professionals and they work and study really hard to do what they do. As for tattoo etiquette in the work place? That’s up to your place of employment.
On the other hand, tattoo’s fit into anthropologie?

A whole class seems to be a bit much. Still, a well-written and comprehensive brochure or booklet surely wouldn’t go astray.

I agree with @iphigeneia about a brochure. A big poster with one of those brochure holders attached to it could be helpful. And maybe put it in with any literature given to incoming freshmen.

They could probably offer this as a course in prison (you know job training and rehabilitation).

The university where I did my undergrad offered a Body Mod course every few years, but it was about the history of body modification and its sociocultural impact.

Any reputable tattoo parlour is obligated to give out care information.

They would then definitely have to do a course on Communicating Like a Human 101 and Relationship Cliches 101.

A whole class is way to much to devote to tattoo care. That would be like having a college class on how to get rid of poison ivy… You could throw in more than aftercare but there really is no point because to become a tattoo artist, one must go through an apprenticeship.

Even shitty artists know to give people a rundown of aftercare. Most shops print out “instructions” and hand them to folks to cover anything that the artist may have forgot to mention by word of mouth. Most artists I’ve seen give people a rundown if they haven’t already tattooed that person. Even if they have visible tattoos, most artists will mention aftercare and encourage questions.

The reason that I’ve found for why people ask others questions like “Can I go swimming with my new tattoo?” or “Can I tan right afterward?” or “Can I set my new tattoo on fire?” is because they want to do these things and even though they’ve been told not to, they think if one person, whoever it may be, tells them it’s ok, then they can get away with doing it.

Ive seen classes dealing with history of tattoos and things like that but for a class on care I find that to be stupid. Honestly, if one has questions about getting a tattoo, google is still where its been for the last ten or so years.

Now, an art class on the art of tattoo work would be pretty cool I must say

A seminar on future tattoo regrets may be beneficial to society.

I’d settle for someone standing on their car in the school parking lot with a megaphone:

The $75 design you picked off the wall of the tattoo parlor doesn’t make you “edgy”, “unique”, or “alternative” in any way, shape or form. Stop making a mockery of something that was once genuinely cool. K? Thx!
