Eigenpun 

When you make a pun by accident, and you don't realize until later, then it's an eigenpun.

(To a skinny guy):

Hey, you look pretty fine today... Oh snap! That was a total eigenpun!

My girlfriend was sick, so I said to her 'you're pretty hot' (referring to her temperature). It was only afterwards that I realised that what I said could be interpreted as referring to her physical beauty! What a great eigenpun...
