When engaged in a sexual act with a partner who has an unusually noisy habit of yelling or screaming "Oh God", "Oh <insert name>", or any other name for that matter. This is repeatedly done until orgasm. Nothing to do with religious banter whatsoever.
Adam - "Mate, that girl i took home last night was singing praises all night"
Steve - "I know, cos I heard it through the walls . . . didn't you find it weird she was screaming my name though ?"
Adam - "She was ?"
