What is Asian grandpa?

A fucking dumbass cook who likes touching you and loves singing some moaning shit like "AYYYYYYYYYYYOAH!" They typically live with you and your parents and don't give a shit about your life. Asian Grandpas would typically wear a polo t-shirt outside during the summer and would always wear tank tops at home. During the winter they would wear cashmere vests and long sleeve t-shirt found in Costco.
