1/5 of a gallon is roughly around 750ml or 25.6oz.....Like da fool who said its da same as 4/5 of a quart is wrong(n its da top answer?)......Theres 4 quarts in a gallon so how do u get 4/5 of a quart? 4/5 of a quart is 6.4oz...If it was 4/5 of a gallon then 5 quarts would be a gallon (Im just saying)
If someone says a fifth that means usually da standard bottle which is 750ml

verb, to plead the fifth

In a United States court case, to cite one's own Constitutional right in the Fifth Amendment to "remain silent" as a defendant, or to not be forced to testify against one's self. This is why a lawyer cannot simply force a defendant into a confession while under oath.

you will look very suspicious when saying it tho

Its a type of party in which everyone must come with a date and a 750 ML bottle of hard alcohol (fifth). However, you must stay zip tied to your date until the two of you finish the entire bottle together. This usually leads to a shit show and everyone gets hammered. Its also convenient because the people throwing the party don't need to buy alcohol other than for themselves. Invented at Santa Clara University.
Joe: Hey are you going to date and a fifth with Katie?
Frank: Hell no, she barely drinks. I'm not trying to black out.

On the 5th Friday of the academic term you celebrate by drinking an entire fifth of alcohol before midnight
“Are you drunk in class right now?”
“Yea it’s fifth Friday I had to start early so I would finish in time”
