A stalker on Twitter who goes out of their way to dig up anything on someone so they can cancel and harass them over social media with a mob of fellow Twitter Sleuths and degenerates. As referenced prior, Twitter Sleuths are the backbone of cancel culture. Without them, Cancel Culture wouldn't exist.
The Twitter Sleuth dug up a 10 year old message on a celebrity's social media account where they said "ur mom gay lol" and they have used this as evidence to start an online flame war for homophobia and sexism.
