The sticky residue left on the male partner's thigh after it has been between a sexually excited female partner's legs during a hugging and 'petting' encounter, often as part of a prelude leading to full sexual intercourse.
"James, there's a strange sticky patch on the right leg of your jeans - I can't smell what it is - do I need to put some stain remover on it when I put them in the washing machine?"

"No thanks Mom, it's just some thigh glue deposited by Mandy when we were messing around during the drive-in movie in Orefield last night."

"OK honey, that should just come out in a normal wash. Just don't you two go too far in your lovin' ."

"Mom, it's OK, we were only making out."
