It comes from magic and magicians. As most people know, magicians have very clever ways of concealing things for their tricks, and one of the most common hiding places for things like cards, handkerchiefs, and so on, is up the magician's usually-long sleeves.
Saying you have something up your sleeve means you still have some trick or idea you've yet to reveal and/or employ (such as, in gaming, some alternate strategy or tactic or a special play you've been concealing to this point).
to laugh is 'rire' in French,and the idiom 'to laugh up is sleeve' is 'rire sous cape'.
Origin "up a storm"
Something Up My Sleeve was created on 1993-09-21.
Nothing. I believe you misheard the idiom "ace UP his sleeve," which means that the person has a secret advantage, as if he had an Ace playing card hidden in his sleeve to cheat at cards with.
It's an alternative way of saying "What's up?"
Magicians and card cheats put things up their sleeves to fool people. Thus, if you ask what someone has up their sleeve, you're asking what sort of tricks they are up to, or what mischief they are planning.
Each idiom has its own origins - you'll have to look up the etymology of every one separately.
If you're a card player who cheats, you might hide an ace card in your shirt sleeve and pull it out so you can win. If you "have an ace up your sleeve," then you have a hidden means of winning something. Sometimes this can be knowledge that the other people don't have, or a surprise person coming in on your side.
Ace up his sleeve, All Greek to me, Apple of my eye and All bark and no bite are idioms. They begin with the letter A.
