Manfant - Full grown adult male encapsulated by a 48 to 60 inch tall child-like body. A short adult male who compensates his shortcoming with attitude.
1. Chris is such a manfant, the dude is 40 years old and is only as tall as my ballsack. What's up with that?

2. Carter came over today wearing a custom made infant bodysuit, what a douchebag manfant he is...

3. Dude, manfant came running around the corner from the living room into the kitchen and headbutted me right in the sack. It hurt so bad, I bout shitted my pants.
