Aliasing anal_plug -> buttplug.

Reason:

Wikipedia says they're not the same thing, but I have doubts over whether the things tagged anal_plug are actually anal plugs and not butt plugs.

Anal plug:
An anal plug is a medical device sometimes used to treat fecal incontinence.These plugs aim to block involuntary loss of fecal material, and they vary in design and composition.

Butt plug:
A butt plug is a sex toy designed to be inserted in the anus and rectum for sexual pleasure.

Oh, you must be joking. OK, my turn now:

Vagina:
A fibromuscular tubular tract which is a sex organ and has two main functions; sexual intercourse and childbirth.

Pussy:
Pussy is an English word meaning cat.

But seriously, anal_plug and buttplug are both plugs and we can say both of them going to anal or butt. Why not alias? I bet they look almost the same.
