‘MeeM’ has originated from YouTube, it includes a wooden medic target that is used in the Team Fortress 2 training.
The sound clip is from if you call for a medic to heal you (Medic!) and then reversed in the middle of the speech.
The wooden medic target has an ability to turn other characters into wooden targets. It has currently appeared
on many TF2 videos, mainly made with Garry’s Mod.
