Meme faces in Facebook chat

Facebook has added dozens of meme faces to their chat and message systems.

To use them you type codes like this in:

• Poker face [[129627277060203]]
• Forever alone [[227644903931785]]
• OK guy [[100002752520227]]
• Me Gusta [[164413893600463]]
• LOL guy [[189637151067601]]
• Trollface [[171108522930776]]

They seem a bit small and pixellated to me. A list of popular codes is here.

Apparently these are profile IDs - not really part of a deliberate meme push by Facebook. Demonstration:
