Semi-significant other

A person you are dating casually, but is potentially a keeper.

I thought you and Kimberly were monogamous.
Well, she is a semi-significant other, but we haven't committed to anything yet, so I'll keep trolling while I wait for her to get serious.

Semi-Pork

its like having sex, but really short. It involves penetration, but its not really long enough to class it as actual sex. It could be caused by someone interupting, a man with very low stamina, anything...

-What happened with you and james last night?
-we got interupted so it was only a semi-pork.
