flush

Your face flushing at an embarrassing moment.

But, just counting the number of flushes doesn’t tell the whole story.

The entire flow of the smaller Chicago river was reversed, in order to flush sewage and wastewater out of the area.

A few might see vivid details, such as the pattern of the hedgehog's quills or the flush of the queen's face.

You know, when you're young and you're you know, shy or embarrassed and you sort of flush all over your face, which actually I quite like doing just in my life.
