There's the two types of Chuggs:
~the "Chug, Chuug, Chugg," with constant sips and swallows, and
~ the long 'Chhuuggg," where the Chugger chugged long and held both close and far before the swallow. The one like gutting a dip before the boss suddenly comes around.
A drunk guy told me this while I was too, drunk.
