Looking up an unfamiliar term or phrase in your
brain, usually without much
success. Most commonly employed when someone else is
talking about a topic you only have the vaguest idea about.
"Every time he tries to talk to me about computers, I have to frantically mindgoogle every other word out of his mouth!"
"I had to mindgoogle my vocabulary
words in class- I forgot to look them up last
night. Needless to say, _truculent_ does not mean delicious and
juicy."
