Someone in Fox News comment section who exposes there disgusting commenters and posts. People such as moesoab48 and democracy.for.us are a few. Moe scares them by using Arab curse words and defending blm protesters. Democracy.for.us calls out the lies of fox itself
A person who competes in Speech and Debate under the sub-category Expository Speaking. They are excellent speakers, wonderful visual aid creators, and generally amazing.
I went to a speech tournament and met the coolest exposer who gave a speech on Coolness.
