The new portuguese expression for being absolutely cool, something being pimpin'. From the portuguese "está-se", which means "we are" (the collective) and the english "pimpin'". It can be written as "se pimpin", but it is graphically more appealing if it is between apostrophes.
"Dubstep is totally 'se pimpin'."
"Jay-Z's Kingdom Come is the 'se pimpin' record of the decade."
