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

Get the a fifth mug.
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.

Frank: Hell no, she barely drinks. I'm not trying to black out.
