A half-way house for strippers. A business chain that allows females to promote their bodies for tips based upon tits, but clothed.
Hooters Restaurant is a safe haven for strippers who found religion, but want to remain in the 'tips for tits' business. Also, allows females to experiment if their sweater monkeys are marketable to go clothed free.
There goes single mom Helen to work at Hooters Restaurant to support her three children. She found religion and quit dancing naked. She now wears a belly shirt, shorts and carries chicken wings and beer in her cleavage for tips.
Basically, a nipple.
As for the origin of it, in the anime called "No Game No Life", Sora, the main character, played a game of word chain, and he said "chikubi", which is "nipple" in Japanese, so the translators had to come up with a word that links "beach" and "bikini", and that's what they created.
At the bar:
- Damn, look at dem hooter nubs over there - I know, mate, just leave it to me, and we'll have some threesome in no time
