Using 反正 (fǎnzhèng) can be a bit addictive as it is seemingly possible to throw in everywher. It means "anyhow", or "regardless"， and is used to disregard a previous statement, particularly those involving options or choices.

Basic Structure

Just put 反正 in the sentence after a comma or pause, similar to how we use "anyways" in English.

Situation to be disregarded, 反正...

Examples
nǐ xiǎnɡ qù nǎér jiù qù nǎér bɑ， fǎnzhènɡ wǒ wúsuǒwèi。
你 想 去 哪儿 就 去 哪儿 吧， 反正 我 无所谓。
G
o wherver you want. I don't really care anyway.

说 不 说 都 一样，反正 没有 人 会 听 咱们 老百姓 的 意见。
Speaking or not is all the same. Besides, no one is going to listen to what we common folk have to say.

不管 你 信 不 信 这个 结果，反正 我 信 了。
Even if you don't believe this result, I believe it anyway.
