Long Bath

When a woman says she is going for a “Long Bath” it’s an opportunity to masturbate without the kids bursting in. Also known as “Playing the Welsh Banjo”

“I’m just off for a long bath love, put CBeebies on and watch the kids for a bit”

Long Island clam bath

When a man attempts the "pull out" method of contraception but waits too long before pulling out. The man ejaculates just as his penis is removed and bathes the woman's "clam", as is often done on Long Island.

I told him to pull out and not get any one me, but instead the schmuck gave me a Long Island clam bath.

Fuck dude, I gave her a Long Island clam bath, I hope she's not pregnant.

I waited too long, gave her the old Long Island clam bath.
