colossal
This word is used to emphasize that something is not just large, but surprisingly or overwhelmingly huge. It can be used for physical objects (like a building) or abstract things (like a mistake or a waste of time). While it is common in both writing and speaking, it sounds more dramatic than the word 'big' or 'large'.

You're seriously short by five hundred. This is a colossal screw-up, Ryan.
Ryan

Maya uses 'colossal' to emphasize the magnitude of Ryan's financial mistake. She pairs it with the phrasal verb 'screw-up' (meaning a blunder), reflecting her frustration and his typical dismissive, low-effort response style ('my bad').
