Pasoori (पसूड़ी) is a Punjabi word, that is actually a way of saying 'Bhasoori' (भसूड़ी). Bhasoodi has also resulted in the Hindi slang word bhasad (भसड़), which is close in meaning to 'chaos'.
In Punjabi, the meaning of Pasoori is somewhere between problem or trouble, especially one that can be avoided, to sheer pointlessness.
Thus, the lines
agg laavaan majboori nu,
aan jaan di pasoori nu,
translate to something like, 'may this compulsion, this pointless trouble of meeting and getting away, go to hell.'
