roflmaonaise 

roflmaonaise is a variation or roflmao (rolling on floor laughing my ass off). The naise at the end makes it appear that the person has written mayonaise, which is completely random. This is usually used to steal crowds of laughing people from a comedic person in a chat. This is can also be a gamble, because if the typer of said new joke does not work, he is shunned and booed and wtf-ed.
