Literally, to poke someone. Typically this is done over an IM client.

Part of the old school emote family (yeah, before lolcats).
Like anything enclosed in asterisks, *poke* is performing the action of poking the person you send it to.

Largely replaced, in modern context, with "/e", "/me" or "/em" (emote) preceding the action.
