erectile misfunction 

While erectile dysfunction is primarily an old guy's malady,erectile misfuntion is the curse of the young man.Particularly the early-teens male is hexed with a penis that becomes erect with little or no provocation.

I saw granny in her mu-mu and popped a boner, I must have erectile misfunction.

Messunderstanding

Messunderstanding is a definition for a misunderstanding but with text messages. As for example a text message intended to be funny or ironic but instead, in the hands of the reciever reads as an insult or is taken too seriously. The misunderstanding is directly linked to the forum of the communication. In ordinary spoken conversation, a weird comment followed by a smile helps the other participant to understand the irony, whereas in text messages it can be misunderstood or - messunderstood.
People avoid messunderstandings by using or not using smileys and/or other stuff.

"James thought he actually could ride in the car with me even though I said no. Why did I put a smiley there? Clearly this was a messunderstanding. I was messunderstood!"

melfunction 

Blind oversight of the obvious in terms of standard operating or operation. Considered to be the middle ground between malfunction and misfunction pertaining to operator error.

The TV was working perfectly normal however the operator could not figure out how to use it. The TV has melfunctioned.
