A really cute way of saying "Reeses". Can apply to both the peanut butter cup and Reeses Pieces, but in the case of the later, is more commonly reffered to as "Reesies Piecies."
These are much more frequently seen than Reeses'. A White Chocolate Reeses is a person who is White on the outside, and brown on the inside (usually Hispanic just like true Reeses).
Not to be confused with a Weaner. While a Weaner is a wannabe beaner (like a wigger is with blacks) and tries to act Hispanic (Mexican) by trying to speak crappy Spanish and wearing Raiders jerseys, a White Chocolate Reeses is actually a white guy who lives the hispanic lifestyle and speaks the language well.
