Perhaps you’re right, maybe my standards are too high? Damn.
Lethal-alien hosts need love too, I guess. 
“On Dates, No One Can Hear You Scream…”
B.O., bad breath, sloppily dressed, dirty fingernails, cold sores, or bad teeth. Further penalty if you don’t even offer to help pick up the tab (I would decline, anyway). Anything else can be overlooked if you have a great sense of humor, a good personality, and/or an ample rack. 
Projectile vomiting, lice, leprosy, rigor mortis, Conservatism.
Bad breath, farts, smelling bad, unkept in an un-sexy way, a snort/cackle - those are all deal breakers.
Fever zit? That too, I’m afraid. I dont have herpes and I don’t want it. I’d be afraid to kiss him. Okay, if I were really in love, at that point I might decide to get infected as well, but if I wasn’t invested emotionally yet? No.
Nose hair? If he agreed to let me groom it, I could live with it.
You do know this is not always a voluntary option, as opposed to say trimmed nose hair or clean fingernails…
So if someone gets a cold sore, should they cancel any dates they had planned?
If they didn’t disclose that they were, and still is a stripper
This made me laugh.
This wouldn’t happen to me. I can not like someone unless I see them first. Then, if the chemistry is there, and its rare for me, then I will like them.
Farting is no problem, the guy I like has a chipped tooth(no these are not related).
Sorry, Charlie. If someone has an involuntary flatulence problem, that won’t go over well with me.
What about if the man/woman is perfect in any possible way, but due to cold, has a visible booger stuck on a nose hair ? How to make it diplomatically be understood ? Repeatedly pinching one’s nose ?

I see what you did there.
Automatic threesome!
Bad manners and eating habits.
I went on a blind date with a guy who was shoveling the food into his mouth so quickly that he didn’t realize major portions of his meal were ending up on his chest and chin. I had to fight the temptation to reach out with my napkin and wipe his face.
It was truly disgusting but on top of that, he was incredibly rude to the waiter – complaining about the quality of the food AFTER he had eaten every bite.
I have no problem complaining about the quality of a dish if I taste it and it is unacceptable, but to complain after finishing it (except what he was wearing) was a deal-breaker.
Doesn’t this exclude all of humanity? This is a serious question, not snark.
If your problem is so severe that you can’t make it through coffee without dropping stink bombs, that’s gonna bother me. The scenario posed by the OP is you chat with someone online who seems cool, with the intent of dating this person, and upon meeting face-to-face encounter a deal-breaking flaw. A deal-breaking flaw for me would be farting all over the place. Sorry.
If the date is with me, yes. Sorry?
Back in college, my best old ex-friend Frank once brought a girl back to our apartment with carnal intent. During the oral part ofthe festivities, Frank realized that he had a need to urinate, and thus excused himself from the young lady’s oral regions. In the bathroom he decided to void his bowels as well as empty his bladder, and spent several minutes doing so. Upon emerging, he was genuinely surprised and unaccountably vexed that the young lady had gotten dressed again and was walking out the door.
His reasoning has always been obscure to me.
I refused a 2nd date one time because the guy moved his lips when he read the menu. I took a lot of crap for that from various friends but the idea of him doing that eternally was a deal breaker for me.
