Semection

Sem-ection.
This is the same as an Eremi and refers to your penis when it is between the semi-hard stage and a full erection.

It's not quite a semi and not quite an erection - it's a semection.

Example 1:
Girl: "Have you got a hard on!?"
Guy: "No"
Girl: "Yes you do!! It's bigger than a semi"
Guy: "I have a semection!"

Example 2:
"Lying beside this girl in bed it may have looked like I was semi'd up but I had a full semection on the go, if she was naked I would've had an erection."

sementitious material

Material resembling male ejaculate (i.e. semen). Not to be confused with cementitious material.

CORRECT: I left some sementitious material in your mom's birth canal last night.

INCORRECT: I can't tell if that is drywall or plaster so let's just call it sementitious material.

semi-filter

To break part of a cigarette butt to ensure maximum tobacco consumption. It was originally done to prevent smoking in contact with the butt that somebody else already placed their lips upon.

I really needed a pack of cigarettes since I was so stressed out so I said fuck and I semi-filtered that single Newport.
