Wheezy is a systematic slur used against asthmatic people or people with breathing difficulties.
This slur exists because Asthma is not real and people who claim to have it are not asthmatic but are deeply mentally ill and have the delusion they cannot breathe.
Examples of how to us this awful slur is "Whats up my wheezys", "She can't be here because she's a wheezy" and "get out of here you wheezy"
