App dating is brutal. Your likability is determined by a few photos and a brief bio that can't be too generic or overly quirky. Striking the right balance is tough, and sometimes you may seem downright annoying.

So what shouldn't you say? For starters, never claim to be the "CEO of [LastName] Industries," as your job title, according to a recent Reddit thread. One user asked the community to describe the "bitchiest, most pretentious/entitled" online dating bios they've encountered, and people had a lot of opinions.

Singletons also hate when you write, "Studied at: School of Hard Knocks." Just admit you grew up in a suburb.

If you want matches, avoid touting that you're "fluent in sarcasm" or "always the smartest person in the room." Redditors agree that people who think their IQs rival, well, everyone, are pretty dumb.

"Only idiots think they’re always the smartest person in the room," one person replied. If you think you’re the smartest person in the room, you are either mistaken, or you’re in the wrong room," a dater chimed in.

Although everyone knows dating sucks, it's a good idea to remain optimistic–at least in your profile.

Guys, females hate when you write, '“Prove to me that this app works' or 'prove to me that not all women are...,'" according to a post. "Like. Get out of here. I don’t owe you anything buddy," one woman wrote.

Men, you're not alone in side eyeing height and salary requirements on a girl's profile. Plenty of dudes list this among the most obnoxious line.

And finally, there are two words that should never appear in anyone's profile: "No drama!"

"Usually means they are just full of it," commented one dater. "They just don't want you to bring your own and sully theirs."
