The "Bahn Hammah" meme is a Pahrak-Va with a Po-Matoran hammer yelling the phrase "BAHN HAMMAH!", which is a deliberate mispronunciation of "Ban Hammer!" Depending on the situation, the meme "BAAAAAHN HAAAMMAAAAAH!" can be used as a variation.
The best part about the "BAHN HAMMAH!" is that it can be used anywhere for anything along with all of the other "Ban Hammer!" refrences in the existence of ever.
- The Pahrak-Va in this photo belongs to Chrismajor2124. Interestingly enough, Chris accidently bought this Pahrak-Va on Bricklink for 5 bucks after advancing too far in checkout trying to find out what shipping would cost. He found out.
