Hello Kelsey, prie from the verb "prier" means to pray or to beg ,in this context it is rather "to beg". Cherie means darling or dear. It either means: I beg you darling , I beg you dear. or "Please ,do " for example if you ask someone" je peux m'asseoir ?" = May i have a seat or sit ? He could answer " Je t'en prie" or " je vous en prie" which means here " Please do".

answer of rachid is fine. "je te'n prie" shows you are grateful and also it's a formula to ask for something politely. the literal translation would be "I beg you".
