Meaning of "Pore on the charm" (?)?

Some examples will be helpful too.

Thanks for your time.
Update: Actually, I read it on a baby's pyjama. And while searching on google for the meaning, I got this phrase: "Ryan, Keaton, Kudrow and Matthau pore on the charm and play off each other nicely."
So, can it be a typo in those 2 different contexts?
Update 2: lol...well Lila, I don't really know where that pyjama came from, just saw a baby wearing it!
