Backwash is often created inadvertently or unintentionally when liquid escapes the mouth during the process of drinking, though it can also be created intentionally by an act of spitting or purposely letting liquid fall from one's mouth and back into the container.
When multiple people drink from the same container, there will usually be some amount of backwash put back into the container; as the number of sips increases, in general, the concentration of backwash also increases.

"Dude, I don't want your backwash." (This person has perhaps declined someone's offer of their nearly empty can of Coke).

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.)

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

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.

Backwash is when particals in your mouth, (eg. food) are pulled back into the bottle by reverse suction.
