Reinforcing the myth -- or fact, perhaps -- of the aloof male, Yahoo has released some Internet user search keywords that show a spike in the number of men who have searched the following: "when is Valentine's Day".

Yahoo also reported an increase in the number of searches for free and cheap things, like "free valentines day cards", up 224 percent; "free restaurant coupons", up 522 percent; "cheap lingerie", up 63 percent; and "cheap engagement rings", up 195 percent.

The top two spiking rose searches have been about yellow and black roses, according to Yahoo.
