Sonphew

A nephew that you treat like a son because you’re NEVER having kids of your own.

I can’t wait to spoil and fill my sonphew up with sweets, then drop him off to his parents.

Sonphew

A son you are the father of because you had sex with your wife's sister, she got pregnant and you produced a child together. (Your sister-in-law's OTHER sons would be your nephews)

My sonphew is always arguing with his little sister over the television.
