As if ridiculi wasn't enough... Ridiculi is something so ridiculous you make it plural, and even then it is still unimaginably ridiculous.
To further explain the ridiculousness of the situation add the word "MAXED". Not only does it make you sound about 100 times cooler, but it reiterates the insane ridiculousness of a specific situation.
Kevin: Dude! I just made a 100 on my AP Statistics Exam
Alex: ZOMG! That is ridiculi maxed!
**The phrase can also be used in pissed off manner or in a shocked manner**
Alex: Dude! He totally stole my art project idea! This is so ridiculi maxed I can't even take it anymore!
