When you lay out a big long turd, then cum on top of it.

The effect is like the opposite of an eclaire. White on the outside, brown on the inside.
Dude, this chick was into some freaky shit. She wanted me to reverse eclaire on her. Shit was weird.

Sexual Act.
Whilst partaking in anal sex, the recieving party will begin pushing out a log of excrement till it makes contact with the tip. At this point, the giving party will ejaculate, injecting his load into the log. This will result in the formation of a Tonbridge Reverse Eclair, which may be decorated with seepage.
Guy 1: Dude, your room smells like shit.
Guy 2: Yeah dude, Emily and I went hard last night.
Guy 1: Did you make a Tonbridge Reverse Eclair, though?
Guy 2: Yeah, dude. It was lit.
Guy 1: Rad dude.
