courtesy flush

This type of courtesy flush is usually performed at home. It's showing courtesy to your family by not leaving any fecal remains in the toilet after you have taken a shit.

A courtesy flush should be performed after the initial flush if there is fecal matter still left in the toilet, or there are skid marks left on the bowl. Repeat as necessary.
I went into the bathroom after my grandmother, and she never courtesy flushed. Infact, it seems like she never flushed at all.

Sex flush

Maculopapular type of erythematous rash.
Masters and Johnson, in their book “Human Sexual Response,” wanted their work to be taken seriously, and wanted to stay a step ahead of the morality police, so they tended to write in almost comically dense medicalese, such as mounting episodes, stimulative approach opportunities and vocalized performance concerns. A sex flush on the stomach was a maculopapular type of erythematous rash. (New York Times)
