n. The facial expression a person makes when they experience overwhelming sexual pleasure or passion. Sexface varies among individuals and experiences however it is likely that a person's sexface is more or less the same in any situation if they are experiencing a climax of sexual pleasure. It is notable that a person's sexface is also similar to the facial expression they make when they are in pain.
Example 1: "When I see your sexface, it appears as though you are in pain but we both know you're not!"

Example 2: Seinfeld: "I don't think I can date her anymore, George."

George: "Jerry, why not? She's perfect for you!! You said so yourself!"

Seinfeld: "Yes, I know, George. I did say that but.....How do I say this...it's...it's her sexface George, it's like she checks out of her body and someone else moves in, and that new person's face is not like hers and it is not very attractive (Jerry contorts his face in an effort to show George) AND she doesn't seem to care or notice. I noticed it in the beginning, I thought I could get used to it, or it might change once the newness wore off, but it didnt, and I've decided I just can't do it anymore. Her sexface scares me, George."

Example 3: "Every time I see her sexface, her mouth forms the shape of a perfect hexagon. It's really impressive."
