Over time female lushes started referring to drinks 1/2 liquor 1/2 mixer or less as Roofie Coladas.
Its first known reference in this way was seen on Facebook in early October of 2010 by a female alcohol connoisseur aka lush in the suburbs of Chicago. That post was immediately followed up with shenanigans of "Me Too" & "I Roofied Colada'd myself again last night" by other women who like to party.
Since then it's quickly caught on & took a turn for the worse when drunken idiots started making "brands" of Roofie Coladas such as Goosey Coladas which were Grey Goose w/ a splash of seltzer water & lime.
Roofie Coladas always seem like a great idea at the time and are fun for the whole family but aren't much fun the next day.
