I have read a lot of online fiction and something that comes up surprisingly often is three people in a clinch of some sort. No, it's not the situation, itself, that is surprising, it's the description of it.
"With those two hot babes, I found myself in a girl sandwich."
Really?
I thought sandwiches were named for the inside, not the outside. That really should be obvious, else all sandwiches would be bread sandwiches.
