recontra

very

extremely

excessively

Sometimes, Argentine's substitute the word "muy" with "re" to mean "very". When something is even more than "very" though, you can say "recontra". This is often combined with vulgar like "recontra puta" (extremely slutty), but is not vulgar in itself. It can combined with "lleno" for example to becmoe "recontra lleno" (really very full).
