A variation of the phrase rofl my waffle where the word "Waffle" is quite obviously replaced by the similar sounding word "wafl" to better match the preceding rofl. Usually used as a lengthened version of Rofl for added humor or to express feelings of shock.
"Did you see it? She nearly killed herself!!! ROFL MY WAFL!!!!"
"Well rofl my wafl, I didn't see that coming!"
