Roflwalrus 

When someone makes such an epic fail, does something so amazingly stupid, or something that's along the lines of "rofl", "roflcopter", "roflstomp" etc., but the situation is so large that it demands for a gigantic mammal's name to be incorporated.

Friend: (reading a pick up line) "I just had to come talk with you. Sweetness is my weakness." Well, then you better stay away from the chocolate fountain, buddy.
You: ROFLWALRUS!

roflsaurus 

The hybrid-being who in essence represents absolute, complete, and undying hilarity. In physical shape, it can be described only as a gelatinous monstrosity wielding not the physical construct that is a body, but rather the characteristics of a cross-breed between the exclamation of 'rofl' and a dinosaur.

See rofl
See dinosaur

During yesterday's regular observation of surroundings, I endeavoured to proceed to terraform the landscape that is my property's front lawn... but lo! A roflsaurus interrupted my labours and struck hilarity into my heart and soul!

roflsaurus 

1. Lit. saurian considered emblematic of comedy, esp. puns and internet based humor. The common roflsaurus is known only to legend but is believed to average a meter and a half in height and to consume banned quotes off bash.org. Their mating calls are said to sound like, "Roofle roofle" ergo the name roflsaurus.

2. Denigratory term for a Forensics speech delivery posture. The roflsaurus involves placing a brief on a table and then leaning over it for a delivery punctured by gestures made with clawlike hands.
Bckgrd. One internet savvy coach got annoyed and called a speech-giver "roflsaurus" referencing both his nickname and his position.

The San Jose zoo recently acquired a roflsaurus that was captured on slashdot.

Ray, stop doing the roflsaurus or I'll make you do another Congress brief.
