When a drunk person gives you advice. It's usually cynical and incoherent, but you better act like you understand/agree with everything they're saying, unless you feel like arguing in circles for a few hours. Those who drunkvise can get pretty angry when their drunkvice isn't accepted as pure genius. People most prone to drunkvising are parents, know-it-alls, authors, egotistical douchebags, and probably Kanye West.

Doug: Watch out you guys, Liam is giving drunkvice again.
