A word described as the romantic relationship between guitarist Frank Iero and drummer Bob Bryar of My Chemical Romance.

Mostly used for fanfictions and certain times with Frank and Bob during interviews and videos. This has mostly occurred from Frank jumping onto Bob's back or sitting on his shoulders.
"Frerard is my favourite pairing."

"Pfft. Bryero is so much better."
