o'kane train
When a girl is licking your cock and you're so ready to get the goods you yell, 'Let's ride the O'Kane Train!' and you give her the full-on dirt bike treatment.
'I'm not getting off this train until you're screaming my name.', Noah to his hot date.
'Ride the O'Kane Train or I'll leave you in the back seat.', Ethan to his girlfriend.
'You're the train, I'm the conductor, and I'm not letting you off until you're spent.', Liam to his hook-up.
