Bored Panda posted a gallery of bad tattoos, taken from the subreddit shittytattoos. Most of them are very bad, in both taste and execution (and some are NSFW), but there are a couple that I find just plain cute. For example, redditor ClearAboveVis10SM showed us his tattoo that was drawn by his wife. She doesn't pretend to be an artist, but she drew this camel for him and he loves her, and now he has a permanent reminder of her efforts to take with him. I find that sweet.
Redditor firefisch actually likes this tattoo, but posted it at the subreddit anyway. This small, simple cat hints at a story behind it, and has a goofy face that's cartoony enough to get away with. I like it.
Redditor watrdog's brother did this tat. It's not highly artistic, but for a ghost it's totally non-threatening and downright cute. There may be a couple of other tattoos in the list that aren't horrible, but the vast majority of them are disasters. See 50 of them at Bored Panda.
