To "tickle one's fancy" means that something is to your liking. Typically, the idiom is said to originate from England from around the 1750s or so.
However, some sources give the original meaning of the phrase "tickle your fancy" another, more vulgar and physical useage for the phrase. Today, though, the general understood meaning is of something being of instant appeal and not regarded as crude in any way. Old fashioned at worst. For example if somebody likes the idea of having a cup of tea they may say "a cup of tea tickles my fancy".
Like so many idioms, the origins and providence of a saying are often shrouded in the mysteries of time or have a variety of attributions put forward to explain their origin.
