Tú sabrás Karate, pero yo sé putazos
I knew what it all meant, except for one word. Wanna try and guess which one?
Yeah, you guessed it. Putazos is the word I just could not figure out.
So, aside from that, we have...
You might know Karate, but I know ???
That was enough to get the gist of things, but of course I just had to know what putazos meant.
I started off with WordReference.com (WR). I figured, hey, do a quick search, ba-da-bing, da-da-boom, and I'm done and moving on to the conquest of the next mysterious Spanish word.
Well, it almost worked out that way.
Here's the link to my thread in WR where I asked about putazos . It explains a lot, and points out that the word means different things to different people.
I still needed a bit of clarification, so I asked my Colombian friend. He told me that this is a bad word, an insult. Shame on me, because I forgot exactly what the corresponding English word is. Anyway, his definition didn't fit the context of the sentence. So I asked my Mexican friend.
My Mexican amigo told me that putazo(s) has a couple of meanings for him. The first one is puto, as in gay. Well, the exact sentiment of puto is probably closer to fag or faggot. To say someone is putazo is to say they are not only gay, but extremely gay. I believe the word we use in English is flaming.
The other meaning of putazos is golpes. Golpes means something to the effect of hitting someone, or giving them a good beating. This seems to be right in line with the context our t-shirt slogan.
So, after a whole bunch of long-winded explanations, I think we can safely translate our sentence as something like...
You might know karate, but I'm good at giving out ass whoopings.
You might know karate, but I'm good at knocking people out.
I'm probably taking a few liberties with my translations, but I think in the spirit of things it's pretty darn close.
Oh! One more thing about the word puto. If you change it to puta, it also means whore. No matter how you say it, it should be obvious you need to be careful with this word, or else you might be the recipient of a putazo.
