it may be tamil. i think you do not remember exactly.
"poh" in tamil means "go"
"Poh yi" mean "after going"
there is no "poh lo mi" i think you are trying "poh la ma" which is "shall we go" or "shall we make a move"
"poh la ma" is coloquial language, the proper one is "poha la ma".
it is not sanskrit.
i am enjoying!! don't you think tamil is easy? it is. just you have to try.
