1 : Partaking in intercourse aggressively enough that the other participant believes there are multiple partners.

2 : A one man train.

He was so aggressive last night, I thought there were eight of them, it was hard to believe it was just a monorail.

monorail 

when a man layes naked on his back while a woman - also naked - moves in such a manner that her pussy glides back and forth, up and down around the man’s dick, much like a monorail train glides on its single rail. Important to know that no penetration is involved in monorailing. Monorailing is made easier as the woman’s pussy gets wetter and wetter due to the friction and motion.

She wouldn’t let me bang her, but she was totally up for some monorailing.

Monorailing is a safer and enjoyable alternative to sex.
