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.
