cari istilah yang lo mau, kaya' the eiffel tower:
Performing a back rub while simultaneously performing coitus with the recipient of the back rub (and coitus) lying face down.

A compound word of fucking and rubbing.
"Hey baby, you want to do some frubbing tonight?"

"Yea, my back hurts and I'm horny as hell!"
