Boom 

Exclamation: Used as an oral exclamation mark but in a purely conversational context. Its function is not as heightened as the afore mentioned symbol so its impact is designed to simply reinforce ones point or statement. Generally found in light hearted, but not overtly humorous, situations.

Dinner's ready.... Boom.

Just quit my job... Boom.
