Big pointy extrusions from a man's chest, usually a source of erotic pleasure, embarrasment, and your mom's dentures.
Did you put sunblock on to protect your manboobies dad?
Ah, manboobies. EVERYONE knows what they are. It's what happens to an overweight man's chest. Not to be offensive. Also, it's what guys get when they get breast implants. Umm....that's really wierd. Guys, don't get man-boobies.
