BRUSSELS (AP) — Feel like having chocolate at Easter in Belgium? Well, send a letter and really lick that chocolate-flavored postal stamp.

The Belgian post office released 538,000 stamps on Monday that have pictures of chocolate on the front but the essence of cacao oil in the glue at the back for taste and in the ink for smell.

Belgian stamp collector Marie-Claire Verstichel said while the taste was a bit disappointing, "they smell good."

Easter is the season for chocolate in Belgium with Easter eggs and bunnies all over supermarkets and specialty stores.

A set of five stamps costs 6.2 euros ($8) but might leave a customer hungry for more.

Thank you for your help :)

Answer

"To lick" (verb) means to pass the tongue along or over something.  A "lick" (noun) is a particular instance of licking.

A "kick" is pleasure or a thrill that a person feels from some stimulus.

So when you lick these stamps, you receive pleasure from the cacao oil in the glue on the back of the stamp.   You lick the stamp, and you receive a "kick."  .....  The stamps offer a lick with a kick.

Answer

A "kick" in this case refers to something interesting or unique, in this case that the stamps are flavored. (idiom) It's really informal and used in this case primarily to rhyme with lick.

You'll also hear that people "get a kick out of something", meaning they find it interesting or amusing. (ie. "Jim got a kick out of the funny video I showed him.)

Hope that helps :D
