IMO, it's worse than that. Assuming Ralph is being true n' honest, the best possible interpretation is he's trying to start a romantic relationship with a Colombian sex worker. That's assuming he/she isn't a sex trafficking victim or a man either.
Now why the hell does he feel the need to broadcast his fantasy? The same reason he wants people to believe he's a rich piggy who could totally make lots of money, if yewww wanna know da troof about it, as well as a really cool boy with lots of friends, does drugs, has the sex, and totally 5'10". Yeah, he wants to convince Adolwulf, his 10 dedicated paypigs, randos on Xitter, the alogs, etc., but he wants to convince himself more than anything.
For what purpose though? No idea. If he can convince himself at the surface level it's all true, and xanny up (washing it down with liquor since it doesn't even work without alcohol) so he doesn't think any deeper, maybe he actually believes it. It's not a great plan, but it explains the Ralphamale's Xanax dependence since I don't doubt he has extreme anxiety.
