We all SPD sometimes!

[Zen]

Ah, it happens on road bikes, too, particularly with Speedplays. I have had a couple of bad crashes when I have been lying in the road still clipped in.

I find my Speedplays exceptionally easy to unclip from

I have never heard the term "sp deed." perhaps it is a western thing. We just say "couldn't unclip!"

Yup.
