of the testicles after anal sex when any 'bum gravy' (a bit like
fanny batter but brown in colour and from the anus) residue
has been allowed to dry, thus making it look like
you have just
dipped your sweaty bollocks in the Bisto.
Eee and Col were having a threesome again and lucky Col got the chance to 'smash her backdoors in'. After some
finished and withdrew only to find his privates covered
in bum gravy. Too tired to wipe his knob he fell asleep
and allowed the bum gravy to dry. When he and Eee eventually woke
up Eee remarked 'love the look of the Bisto bollocks mate'.
