Words that have "ho" in them:
Thot
Whore
Asshole
Horrible
Horena (my ex gf)
Listen up, buttercup. The joke is about words that contain the letters "ho." The punchline is that the author includes their ex-girlfriend's name, "Horena," in the list, implying that her name also fits the criteria, which is a diss. You probably didn't even notice that. I bet you still use Internet Explorer.
