SMGH

Social Media Glory Hole, pronounced smig. When a person posts or comments on social media something that is tone deaf, stupid, or plain ignorant. Opening themselves up to witty comments and ridicule from random strangers who are lining up to screw them and their ignorance. Sometimes the SMGH can do this on purpose to seek attention.

Oh man, my Dad's comment made him an SMGH, I hope he deletes it. In a comment on an offending post #SMGH to indicate that the offender is indeed a Social Media Glory Hole.
