Cilantro

The cilantro in-joke appears to have started due to this post, in which well-loved mefite/metachatter interrobang attempts to get others to hate cilantro. Several people agreed with him, but it is at this point unclear whether the cilantro in-joke is making fun of interrobang or not. Either way, cilantro sucks doesn't suck could make a horse gag from twenty paces is super yummy tastes like the kind of barf you would barf if you first ate a whole pot of barf, and then barfed it onto a pile of dead pigeons is an essential delicious part of many world cuisines is a regrettable misconception on the part of a blind idiot god is green and harmless and never did nuttin' to nobody was created by satan and may be initially tempting, but is in fact quite evil.

Damn you, Satanists!
