The act of not coming through on a promising flex (shag).
The phrase originates from Matt going back to Blackpool Jackie's place after a hook up in Rumours. Despite numerous attempts to get past the heavy petting stage- access was continally denied and Matt was left to lie awake in a state of flex limbo until 8 next morning, when he received a plate of cheese on toast for all his hard efforts.

It must have been a particularly good meal as he returned the following 2 nights and received nothing but more cheese on toast.

This term describes the spreading of a female's legs the morning after an evening of vigorous and non-condom-wielding snoo snoo.

The congealed residual baby batter combined with the love lips being 'peeled apart' is comparable to the opening of a toasted cheese sandwich.
Franz: "We just passed out after an exhausting romp!"

Lucile: "Oh god opening my legs this morning was like peeling apart a freshly toasted gouda pocket, a real toasted cheese sandwich."

Franz: "Don't ever talk to me again."
