G.H.B.
A Northern Irish way to say you're getting someone to have sex with you, like you're the main event
He said, 'I'm gonna G. H. B. her tonight' and left the room like he was going to war
She texted him, 'You better G. H. B. me before I leave' and he replied with a wink
They were at the bar and he just said, 'I'm gonna G. H. B. you later'
