Any man whose beer belly prudes out over his waistline causing a look of pregnancy. Side effects include low testosterone levels (man PMS), lactating man boobs, and sempiturnal diarrhea of the mouth.
DAMN, Jimmy's caring a man baby! Yeah I heard he's due next week. Well at least it matches his man boobs.

A man baby can be described as a rather tall warehouse manager that gets particularly sad and/or angry when he does not get his way. Although he is tall and strong he does not want to be exploited for his manly qualities; he will not help his lovely coworkers by lifting boxes, carrying soda/water, or bringing them tables. If you see this man baby in the wild, beware of his shirtless side kick, the elusive finance manager. Don't let him fool you with his charming cackle; he has been known to cause spontaneous nose bleeds as well as convert an entire office full of well-meaning people to cussing bandits. The finance manager will always say "I told you so!"

A full grown man who looks like a baby, and acts like a some type of awkward child. This usually includes being short, having an excess of fat, and protruding lips and/or brow. Usually to be classified as a "man baby", this person is encountered in a comic shop, an online video game, or as a dysfunctional co-worker that the manager keeps around either out of pity or relation.
I was in line at Best Buy for halo 3, and this totally sweaty man baby was ahead of me buying several weeks worth of anime porn.

This phrase is descriptive of the 4 disticnt levels of courtship used by females to describe her involvement with a man.
1. baby- you are involved in casual friendship based on sex
2. boo- she not only gives you sex but lets(actually tricks you into) you buy things for her.
3. man- you are in a full blow relationship, have also been coerced into meeting the parents of said succubus, and dont have any plans for leaving. She still has sex with you but its getting harder to get action because she doesnt want it to be just about sex and wants to take the relationship to a higher level, and she still manages to con you into buying shit for her.
4. bitch- the final twisted stage, where the female truly has a man wrapped around her devious little finger and is actually able to yell at him, take his paycheck, and sleep with him only when she says it is ok, and he takes it like the bitch he is because he has been so severely brainwashed he actually believes he has it pretty good. This is when all 4 categories are strung together to make the worst label in history; baby-boo-man-bitch. At this point you have been completely and utterly owned by a female that you told your buddies would never break you but she just did. Once this label is placed you may as well throw away your cell and move into the mountains where no one knows you. This usually occurs right after the wedding or honey moon.

A man--usually over 50, but not always--who thinks he knows everything, and loves to talk at length about anything. It is futile to try to interrupt or correct him. While he claims to know everything, he is unable to take care of himself--can't cook a meal, has to ask his wife his underwear or shoe size, doesn't know how to clean a toilet or operate a washing machine.
Dad is such an old man baby! At dinner last night he spent 20 minutes expounding on the virtues of investing in silver, then when it was time for dessert he had to ask mom which kind of ice cream he liked.

An old hairy man that wears a diaper and goes around saying "Daddy", "Mommy" or anything of that sort.
"Mmph, you sexy man baby, get out of my house."

When you dress your infant son in adult-like clothing such as jeans and collared shirts such that they look like a miniature grown man.
Look at that little grown man baby!
