push her stool in

Used to describe anal sex in the presence of mixed company.

"Mom: Good morning, Bobby. What did you do last night?"
"Bobby: I met a friend at a bar. I had to push her stool in."
"Mom: That was very gallant of you."
"Bobby: Well, Mom, you know me. Always the gentleman. Do we have any bleach?"
