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.
