In Maison Ikkoku, the title of episode 60 is "見ちゃった！響子{きょうこ}と三鷹{みたか}がいきなりB？！",
which is translated to "Caught in the Act! Kyoko and Mitaka-Hot and Heavy!"

My question is, what is "B"? I've literally never heard it before @.@. I know
"H" and "BL", but I've never heard just "B" to have any meaning in that way.

For context, this is an 80's/90's anime, and Kyouko and Mitaka are a potential
couple that are caught embracing (in a misunderstanding where Mitaka fell on
top of Kyouko) by Godai, who's also after Kyouko in a love triangle.

"B" meaning "hot and heavy"?
I assume this is [sense 12 in this
dictionary](https://www.weblio.jp/content/B), although I haven't heard the
term myself as a learner.

> 俗にペッティングのこと。Aをキス、Cをセックスとして、その間の段階ということから。  
>  Colloquially, (sexual) petting. From the fact that if A is kissing, C is
> sex, then B is the stage in between.

If this definition is correct, an equivalently colloquial English translation
with a pretty much identical meaning would be ["second
base"](https://en.wiktionary.org/wiki/second_base).
