surfing jargon

[possopo]

the narrator is a surfer talking about some place in france:

"there was this perfect pipe, it was like two miles out and it was so perfect, it looked like backdoor."

does someone know what backdoor means in this context?

Hope that this link may help you:

And also I found out that backdoor is something "similar" to pipes. Which in this case means something in relation to surfing.

ok, i googled around and just found that backdoor was refering to a way to enter the pipe.

your definition makes more sense, thank you:)
