Kubbu is an onomatopoeia used by certain people of Valluvanad and Madhya Thiruvithankoor regions in Kerala. Kubbu is someone who makes annoying sounds and gestures to irritate people. Kubbu is also a facial expression or sound ( similar to bruuu) that annoys everyone in the world.
suprisingly, the 'k' is pronounced. knublets are nubs that sway back and forth when they get nervous or excited. in tense moments, knublets can be observed swaying at high enough speeds to generate a distinct humming sound.
