“Hopefully the rightwing-o-sphere’s infatuation with this dingbat will be over soon.”
“I still find it funny when I come across an obscenity which has been the victim of a literary bleep; using a couple of dingbats in a four letter word does not lessen its impact.”
Something or someone that one vehemently dislikes/ A strong curse.
