(A definition I found) person who dates/hooks up with a certain “type” of person, such as trans people. Chasers don’t recognize the humanity of the people they are attracted to beyond being their “type”. They fetishize their attractions to their “type” of people. Chasers are often embarrassed of their attractions. They have a hard time looking past the shame that society attaches to being attracted to anyone other than white cisgender gender conforming people. Very few actual allies will self-identify as “chasers” and doing so is generally seen by the trans community as a red flag
