Lautzenheiser Share definition Flag A really long ass last name that no one can pronounce right, let alone spell. Comes from the German language meaning "Loud through the house". "What's your last name?" "Lautzenheiser" "OK...I'll just call you by your first name" Lautzenheiser by Evedora March 5, 2009 Get the Lautzenheiser mug.
