The Charles River is a form of Jungle Juice that is made of roughly a half of bottle of Everclear, a half litter of Tequila, roughly 6 cans of light beer, a mixture of pink lemonade and yellow lemonade and some packets of sugar. It looks extremely nasty but it gets the job done. Also if you throw a condom in the mix it will look like The Charles River in Boston.
Guy1: Dude, that Jungle Juice looks like the fucking Charles River
Guy 2: Dude, it IS the Charles River; it'll get you fucked up.

Get the The Charles River mug.
River that starts in Hopkington and dumps out into Boston Harbor, seperating Boston and Cambridge. If you go to the Charles, you will likly see some smuck floating around, maybe a few condoms and dead birds as well. People row on it when its now winter and completely frozen over. It is famous for the Head of the Charles, a huge rowing regatta with tons of teams.

It is incredibly filthy, but I have swam in it and I am still alive today.
Son: Mommy, I touched the water in the Charles River with my finger.
Mom: Oh no, let's go to the hospital.

Get the Charles River mug.
The old, accumulated, and grimy cum that floats to the top of the Charles River in Boston, MA. Usually skimmed off with a fine sieve and utilized in a wide variety of usually Italian-American cuisines. Also may be captured through trawling the middle depths of the river for a more moist, gelatinous, “mozzarella ball” like consistency. Similarity to the Charles River Regatta intentional.

Note: “Ricotta” must be pronounced like a shitty, Soprano’s obsessed, third generation Italian-American (i.e. “Chals Rivah Riggot”).
You know what this manigot (manicotti) really needs? Some Chals Riva Riggot (Charles River Ricotta)!
