Hilariously weak evidence aside, Rubio has talked about foam parties before in interviews.
Below, he tells Jimmy Fallon, “The truth is, when I was in college I bought some boots like that, and remember the old foam parties? Remember that? You don’t remember that…I bought some of those and when I left the foam party they were white. Because the foam washed the dye out of it.”
“You used to go to those dance parties?” Fallon asks.
“I went one time,” Rubio responds.
