PLAT TERRAIN

This was in the Henrik and noah secret pranking hangout where he was making pranks, when he was giving me a good prank he said "What up" "Good" "What do you wanna do today?" "idk i plat terrian" "what was that!DRRABBITEARS2020" "what" even he was confused on what he said. later he said it means "Flat world" or as therioized "Play terraria".
