When someone tries to spell something correctly but instead spams random ass characters for no fucking reason, its often annoying and extremely excessive. So if you see someone spamming gibberish or random ass characters, all you have to say is GIBBERSHIT.
When someone cant describe something through words because the subject is too awesome to handle. This is done through text usually, but when used in person the result is ending up making everoyne laugh and/or look at you crazy.
Person one: Hows the book going?
Person two: hfjdfdgdgfdsgjfgdfyefhg<---thats how the books going
Person one: This is awesome. Its like hdfjkhfjfh
Person two: Really? Gibbershly good?
News reporter: Well all i can say on this matter is hfjsdhfhf
Someone at home on the couch: LOL Was that for real?? *laughs*
The act of texting random Jibberish while driving in commute traffic, effectively rear ending one car, forcing that car in to two other cars, causing a four car pileup and you end up shitting your pantsin the end.
