A Barnsley
A semi-erect penis that appears outta nowhere, like when Barnsley shocked everyone by getting to the semi-finals in 2008.
"Barnsley with an unexpected semi!", the commentator, who probably hasn't had a proper meal in weeks
My mate got a semi when Barnsley made it to the semi-finals, I don't know why he's still single
I had a semi-erect penis at the FA Cup semi, all because of Barnsley
