What are the best top replies you have seen on twitter?

Also, why do they not work for some people and why do they disappear sometimes?

There's always a Lana Del Ray troll constantly in the top of every pop celeb's mentions with a funny yet disgusting reply lol

Usually the top replies aren't funny, just try-hard.

they're always cringe worthy

Anytime I watch Miley's replies, the top reply is an insult
