zloorp ("slurp") is an exaggerated cuddle word used in the furry fandom to indicate ridiculous licking, as a sign of affection, silliness or randomness.
Zl00rping is entirely possible in real life, it is not limited to being an Internet emote as real dogs that lick alot tend to "zl00rp" as well.
Alternate spellings: zl00rp, zl00rpz0rz
zloorp as an emote in conversation:
Furry A: "Hi. ^^"
Furry B: "*zl00rp*"
Furry A: "Meep *zl00rpz back*"
