6) He smells.
That isn't to say he's not fun to be around most of the time, or that there is a gross odor which lingers about him. That's not what I'm talking about at all. What I refer to is his ability to smell, as in detecting various aromas via his nostrils. Do you really want to be around a man with such a dangerous capability? Imagine walking around a corner and out of nowhere he says "is that pizza?" You ask him "how can you tell?" And he responds something about how he can "smell" it. That's some messed up crap right there. Sure, it might not seem like a big deal then, but think about all the dark magic he could conjure with such supernatural abilities. He probably interrupted something important you were saying when he referred to his pizza senses anyway, which is totally rude.
7) He doesn't know what bacon is.
If he ever asks you "what is bacon?" just drop him immediately. No exceptions. Even if he knows what bacon is and he's asking questions like that, it shows his lack of maturity. Such an inquisition may be the start of a joke which I can already tell is not funny, and you don't need a man who isn't hilarious and perfect.
8) Bird stool on his pants.
Or dog stool. Any type of stool, really. If it's on his shirt or shoes, that's not great either. Basically if you're around him and the word "stool" pops into your head, that's a deal breaker. Your subconscious knows more than you ever will, so trust it. Also, if intuition tells you "diaper" or "diapers, diapers," that means his dumb brainwaves are getting all up in your zen. That's an invasion of mental privacy. In fact you should get a restraining order.
9) He's a jerk.
Jerks are jerks.
10) He says he loves you.
Scientific research shows that males only talk to themselves unless speaking in third person. So if your boyfriend's name is Frodo (guys named Frodo is sign number 17 [not in this list]) and your name is Genevirfathena. If he doesn't explicitly say "Frodo loves Genevirfathena" or "Genevirfathena is beautiful," then he is talking to himself, so usually what he's really meaning to say is "I (Frodo) am beautiful" or "I (Frodo) love me (Frodo)." Saying "your beautiful" could mean anything. He should know better than to send mixed signals like that. Talking in third person is the only solution. But if he's talking in third person a lot, dump him, because talking in third person sounds weird and gets annoying real quick. Silence is best. That means he's listening.
11) He wears corrective lenses.
12) This last one is disappointing.
(It always is) If you are ever disappointed for any reason, break up with him, because that means he can't keep you constantly satisfied. While you were reading this, he may have jumped all the hurdles until the point, but just do yourself a favor and tell him it's over right now, because I can tell you're disappointed. He's stupid enough to let you read this article and find out the truth about him and get all bummed out, so just get it over with. You need someone who can keep you happy 24/7. That's the definition of a perfect relationship, anyway.
