When a guy sprays cum in a girl's eye and then slaps her with his dick, just because he feels like it.
'He surprised her with cum in her eye and slapped her with his dick.' 'That's the procedure, that's the procedure.'
'He did a procedure on her and then slapped her with his dick.' 'That's not a procedure, that's a procedure.'
'He had a procedure with her, and he slapped her with his dick.' 'That's the procedure, that's the procedure.'
