It's called Phrygian "Dominant" because it's just the Phrygian mode with a raised 3 (which gives it the tritone between the 3 and 7 like a Dominant 7 Chord).
And pick really close to the bridge. It's totally cliché but fun.
You can also make Lydian Dominant with the same trick (just lower the 7 in Lydian). You can hear Lydian Dominant in the Pee Wee's Big Adventure soundtrack.
