backwash

The filmy, cloudy residue at the bottom of a drink that you get when you pass a drink to someone else. Always seems to be at the bottom, separate from the rest of the drink, like oil and water.
Also a good way to determine if someone has eaten fish or tomatoes recently.

Soph: Can I have my coke back, now?
Tat: Yeah, here you go.
Soph: Is that backwash at the bottom?
Tat: Er...
Soph: You keep it.

(incidentally, if anyone gets a bottle with backwash in the bottom, try refilling it with its original liquid as well, so it's full, then heating the bottle from below. Because it's seperate, I wonder if it behaves like a lava lamp. If anyone wants to try this, feel free to enlighten me.)

backwash

to take a mouthful of drink from a container (cup/glass/bottle) and spit it out back into the container in which saliva and bits of food go back in with the drink

Someone eats a carrot sandwhich and becomes an arsehole by taking a mouthful from their cup and spitting it back in which bits of bread and carrot go into the drink with saliva=backwash

Backwash

When a guy or girl cums in your mouth and you hold it in your mouth only to deposit the goods into their mouth

Man that chic looked like a geyser when I give her a backwash. Dude that's awesome. Next time I see her I'll call her old faithful.
