Vandalove
The act of decorating a loved ones property, usually their car, with excessive items (window marker messages, silly string, bows, ribbons, flowers, etc.) meant to publicly display your affection for your loved one in the most obnoxious way possible.
My coworkers and I were heading to lunch when we discovered that my girlfriend had totally vandaloved my brand new car with bows and ribbons and a huge I LOVE U written on the windshield!
