If you look up ojete in the dictionary, it means "eyelet". Well, that's one of the definitions anyway. And unless you have a really good dictionary, it probably left a few things out.
Ojete is also a vulgar word for ano, or anus. In English we would say asshole. This is where today's sentence comes in.
No seas ojete
Don't be an asshole
And like always, there's more than one way to skin a cat. Or in this case call someone an asshole.
Some other good options are "pendejo", "cabrón", "culero" and in Spain "gilipollas". These are all probably understood by most Spanish speakers, but remember each country might have it's own words for these things.
The good news is the fun doesn't stop here. Ojete can also be used as a synonym for culo. Let's look at a few examples.
Se puso tan cachonda que hasta me dejo darla por el ojete
She got so horny she even let me give it to her in the ass
Una web dedicada exclusivamente al mejor porno hardcore por el ojete
A web site dedicated exclusively to the best hardcore anal sex
Le rompen el ojete
They gave it to her in the ass
That's it for today, espero que te sirva.
