Puta madre

[Sonia]

Spanish slang. Puta means roughly fuck or bitch, and madre means mother. The two words toghether become a common expletive meaning holy shit or mother fucker.
In the north of Spain, if the article la (meaning the) is added to the beginning of the phrase (la puta madre), it becomes a high compliment meaning that something is the coolest of its kind (similar to calling it [the bomb], or [the shit].)

[Becky]

All over Spain, de puta madre means extremely good, appealing, desirable. It applies to people, situations, experiences, anything.

[Sonia]

The Peruvian style (mostly in the south) of expressing anger or disbelief. Sometimes people just say [puta] - although when you add madre after it makes the saying more explicit/severe.

(literally means: mom-whore - - chat abbv.: pm)

In other words its a spanish version of how english speakers say Holy Shit

[Donald Trump]

The only spanish phrase your friends say because you tell them what it means. They use this phrase to offend spanish speakers in the area.

puta is Spanishs Castilian word for fuck and madre is a word in spanish used for mom and spanish in Englishs point of view switches the descriptive word with the noun henceforth puta madre translates into mother fucker. puta used with other words can change its meaning some words with a at the end can be directed to woman as whore or bitch, usually when the word it combines with is has e or o at the end is made fuck and directed at men. But all you really need to know is that that if it is directed at some one it is an offense if at no one or randomly said it is an exclamation.
the word is Spanishs most commonly used swear word it is just as abused as the English word fuck
