woah shamrock 

After the viral video of the same name where a racehorse bolts off with an inexperienced rider on board: A feeling of being totally out of control in a dangerous situation where the only certain outcome is that it's not going to end well.

Halfway round the roller coaster ride I freaked out and was like "Woah Shamrock!"
