Ive never heard of it, show me more pictures of the stuff youve bought
A really popular brand of shirts in spanish is the mexican "NaCo", what they put on their shirts is really funny. I think the website is naco.com check it out
In spanish from Spain that phrase is very used. Like "Me la estoy pasando de puta madre" (Im having a great time)
Since that phrase's not really used in Latin America it wouldnt be funny (classy) to wear something like this for example
but if I lived in America Id wear them without a doubt. I really liked the one with a picture of the Virgin Mary that says "My first love"
