When a males penis is neither erect nor flaccid, but usually somewhere in the middle. This usually happens without a male being aware of it, or if his penis is slightly aroused. This can result in embarrassment or satisfaction depending where this occurs, and the occasion.
Example 1:

John: "I love the amazement in the other kid's eyes when they see my junk in the change room. They think i have genes from the black mamba when really i just have a halfie!"

Sam: "What is a halfie?"

John: "It's when i arouse my penis just a tad so that it looks like my penis is bigger."

Sam: "You really fooled me, i thought you where born that way!"
