Such an occasion is responsible, I fear, for the word slubberdegullion.
Luckily the word has more or less vanished, now - unless, possibly, you're a Flowerpot Man -
- but it means...well, it's obvious what it means: an untidy, grubby and/or worthless person.
(Not that there is such a thing as a worthless person, obviously.)
If you do hear this horrid word then pity the speaker. He will be either someone with no idea how humour works, an entertainer of three-year-olds, or someone desperately trying to rescue a comedy.
Sunday Rest: slubberdegullion. The slubber bit is probably a dialect form of slobber, and the rest has been attached because it's just so side-splittingly hilarious.
