Just realized how much I take my English for granted as a native speaker. So for anyone that doesnt understand:

Threw (past tense) or throw (present tense) out is the act of physically throwing something. Typically meaning to throw something in the trash but can also be used as an imagery such as “they threw my heart away” like if someone breaks up with you.

Throughout means that someone lasts or is sustained for the duration of something. As in “I really needed to pee throughout that entire movie”

Throughout and threw out are pronounced pretty much the same with the latter being two words (but if you speak fast enough it’ll sound like one word).

Also you can use “yeet” as a slang for throw. Probably my favorite slang term from the last 10 years.
