A co-worker or acquaintance who is less than amusing, annoying, sometimes deceitful, and can cause negative feelings toward others around him. However the person referencing the “good guy” is perhaps of the same definition therefore defining himself as a “good guy”!
He’s a good guy, but I would not want to be around him outside of work.

Lazy as all get out, but he’s a good guy!

A male who despite being caring and respectful to his female friends and acquaintances will never become anything more than "just a friend" to them. These guys will often pay attention and offer advice to their attractive female friends problems about their arrogant, douche-bag boyfriend only to see her dump that asshole and end up with someone even worse than him. This is because the majority of women, especially in their teenage years want to find muscular, good-looking, fashion conscious, pricks with enough confidence to diminish their insecurities enough so they can sleep at night without cutting themselves or consulting bulimia. Unfortunately this leaves the good guy in the shade, despite him being a better person, and being ten times the man her boyfriend is. Usually when girls say they want a "nice guy" he's usually some pantload with a foreign accent and a weird hairstyle. Luckily not all girls are like this and when the good guy finds these girls, he'll realize good things come to those who wait.

An internet meme appearing on 4chan, Reddit, and other sites about the classiest guy around. The meme involves a photo of a smiling, confident, stubbled guy smoking a joint and giving a friendly reassuring look toward the camera. On top of this photo, people will write of Good Guy Greg's classy deeds. He borrows your car and returns it with a full tank of gas. He parties with you on your birthday but never tells anyone about how you puked on yourself. He comes over for dinner and washes the dishes. He is better than you in every way, but never talks about it and makes you feel better about yourself instead.
Good Guy Greg: Borrows $5. Pays you back $10.
