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.
