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!"

Halfie, is when you take a selfie, but only of half your face, or body. It can be either half your face, (upper, lower, only one side) or half your body (upper, lower, or the sides)

The halfie phenomenon is a Norwegian word, invented by a globetrotting guy from the west coast, on his travels to Paris, he discovered a way more interesting way to take pictures of himself in his endless quest for likes on various social media sites. Halfie is now taking the world by storm starting with Norway and Paris, and quickly spreading to the United States.
He took a nice looking halfie.

Selfies are so 2013, it's all about them halfies now a days.

It's half of a selfie. Popularize by instagram user @thankshane in early 2014. The main goal of the halfie is to capture something unique or interesting in the background, with yourself in the foreground.
Did you see Sam's #halfie? He had Justin Beiber in the background!
