The word itself was first used and invented by the ever tipsy Danish and Swedish people(the real vikings), where alcohol is the cure to everything.
It is even said that alcohol can cure tipsyness... if you get enough.
-Wauw tipsyness is ftw! Give me more!
-Look at that hot swedish chick, looks like she's got some serious tipsyness there!
-Argh! I need tipsyness!
-Where's tipsyness? oh there's tipsyness.. Wiiiiiiii
