When you decide to look up something on google or youtube, by writing words that may be tags, regardless of whether what you write makes sense at all.
*Tags here do not refer to tag, but keywords people put in their videos so they can show up in our search results.*
Guy 1: Dude! You have to see this video on youtube it's so funny!
Guy 2: Cool! How's it called?
Guy 1: Crap, I forgot... umm it was something about frogs and sticks and shit..
Guy 2: Don't worry man, I'll tag search that shit up.
A google search rant is when youre mad at a family member or something, and you just type(but not search) things mean about them in the google search bar.
