Oh I guess you're right. Although slurp isn't so much more explicit IMHO, I'm just used to it because it's commonly used with perl, but I don't think I've ever seen it used for any other language.

To "spew" in contrast also means to vomit.

As a native speaker, I can tell you that "spew" here is completely natural. It's not a synonym of "vomit" and does not carry the negative overtones of that word. It's also not the same as "spit", for the same reason, as well as implying a different (greater) volume of matter being ejected. :-)

Not super common but it is a euphemism for vomit. There is a rather amusing pun about it in Egil’s Saga—Egil drinks till he’s sick and stands to nearly smother his excessively loquacious, one might say logorrheic :P, dinner host in vomit. When the dinner party responds in angry shock he says, paraphrased: He was spewing all night, so you can’t be mad at me for doing the same. It’s worth noting that vomit probably has 100, easy, synonyms/euphemisms/idioms in American English.

After second thought ...

It's "slurp" - eating noisily - which is the misnomer.

To gulp would be a more accurate description for devouring a whole file.

Spew would fit then.
