The act of transporting your case of Nati Ice while rocking the utmost frattire, along with hoisting your prized case on your shoulder. In simple terms froisting is a combination of "Fratting and Hoisting". Froisting usually occurs when you are approaching a frat party with your frat bros.
"Dude, Bro!. I am straight up Froisting down Clifton Avenue! Let's Bro-out in ten."
