Truly truly wellensittich,
Das ist ein guten tag wellensittich!!
Unfortunately thats as far as the lyrics go - but there are amusing actions. They include resting your head on your hands, widening your eyes, cocking your head and having a demented smile whilst singing the lyrics and including random snippets of german and english. Used rarely - if you hear a girl saying ' Oh wellensittich!' i suggest you approach her - she is very inventive, witty and beautiful.
Bella: Hello wellensittich!
random person: Did you just say wellensittich? No wonder you're such a witty, inventive, beautiful girl!
