Back Freeze

Back freeze, or ice cream backache, is an intense pain in the back caused by eating or drinking something cold. It’s not serious and goes away in a few seconds or minutes. If you get one, try to bring the temperature in your mouth and throat back to normal.

Man that Sonic icee really gave me a back freeze.

Splash back

When you take a heavy shit, and the water splashes back up, soaking your butthole. Usually in reference to an overused port-o-jon.
AKA stank water wash, mud cleanse, poor man's bidet.

There's nothing worse that dropping a duce in a port-o-jon that hasn't been pumped out in weeks, and getting a splash back.

back photo

When on social networking sites 'back photo' is the act of clicking on the 1st Photo and then when viewing the photos, instead of going forwards, you go backwards. Mainly this is done to reveal people's embarrassing hair styles and choice of attire.

This Fit guy just added me, I hope he doesn't Back Photo Me
