The process of taking a shower when the drain is clogged with hair or other funkiness, and the tub fills with water while you're in there.

Can also be used to describe the actual tub you are trying to shower in, but standing ankle deep in water...
Hey girl. Can I come shower at your place? Mine's a total ankle bath right now, and I don't feel like dealing with it.
