lmaonaise is a derivative of 'lmao' - laughing my arse off. it can be used to express the extreme amusement of something whilst relating to the popular sauce which so many of us put on salad: mayonaise.

Other examples include lolcakes and roflwaffles.

Laughing my ass off - not actually. I speak exaggerations.

Making fun of white people and their mayonnaise fetishes. Please note, people who use this term are usually hypocrites because saying words from the strange language of L33t Sp33k in real life makes you a nerd.

L33t Sp33k:
OMG zOMG If YoU uNd3rSt4nD tHiS yOu'R3 4 fRi(k3n N3Rd lololol LMAO n00b pl0x*

*excuse me if the translation is not correct, but I'm not a fucking nerd (well, at least not to big of a nerd... OK I admit it I'm white)
Haha, look at that f**king nerd, LMAONAISE!
