ergosphere

A place in the woman's vagina where not many men dare to go

Yo son I took it to her ergosphere last night!

Ergosphere

The region of space close to a rotating black hole from which it is possible, in principle to, extract energy.

The outer boundary of the ergosphere is called the static limit.
