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.
