To do a fad or trend to try to reinvent the 1990's akin to rollerblading, skateboarding, hula hooping, yoyoing ect. Or trying to bring back good feelings with nostalgia from the 1990's (i.e.) Tomagachi, Furbies, or Pokemon.
I forgot I had some 90'sing to do before the film's intro. (Proceeds to grind staircase guardrail with skateboard).
