“The volume inside of this bus” or “the volume on this bus” is a comment seen often on TikTok. It means the TikTok video is relatable to the viewer.

“The volume on this bus” is a shortened version of the phrase, “The volume on his bus is astronomical.” That was derived from TikToker @SnarkyMarky’s Feb. 8 video captioned, “POV: you’re on the bus ride back to school after a field trip and the teacher is yelling at you because your class is too loud. In the video, he yelled, “Ladies and gentleman, the volume inside this bus is astronomical.” The video became very popular, accruing over 14 million views and 3 million likes.
