Help with a Russian word?

[savannah]

Hey, can someone help me? what does "dvaju mat" mean? it's russian...

[Vlad]

it means that speaker admits s/he had sexual intercourse with your mother...

[Jason]

One of the "swear" expressions used, the only one close to English I can think of is "Your mum/mom"
And yes, it does appeal to sexual intercourse with "your" mother.

[Aleksander]

Tvoyu mat' is an exclamatory phrase that can indicate a wide range of emotions: joy, anger, surprise, shock. E.g.: F**k, I've lost the wallet. \ Твою мать! Я кошелек потерял.
Here are some real-world examples on the twitter (it's always great for finding the context):
