the.com/bombast

means Speech or writing that sounds grand and important but has little real substance behind it.

from Comes from 'bombace,' the old word for cotton wadding used to pad and stuff clothing — ultimately traced back through French and Latin to the Greek 'bombyx,' meaning silk or silkworm. The link is pure physicality: just as padding puffs out a garment to look fuller than it is, bombastic language puffs out an idea to seem weightier than it actually is. The word shifted from describing stuffed fabric to describing stuffed rhetoric by the late 1500s.
