The word pare can mean two different things in Tagalog.

It could be short for kumpadre, meaning 'friend.'

Kamusta, pare?
What's up, dude?

Pare could also refer to a priest, although the word in this sense can also be spelled as pari.

nangumpisal sa pare

confessed to the priest

Tanungin mo sa pari. Siya si Padre Damaso.
Ask the priest. He is Father Damaso.
