The act of publicly Virtue Signaling your acceptance of foreign religions and cultures. (Sineading on social media)

To "Sinead" means to act morally superior by being publicly accepting of everyone.
Why does Brianna feel the need to Sinead on Facebook? Its really annoying that she acts so holier than thou.

Stop Sineading Brianna! We get it, you think your shit doesn't stink.
