MAC Impassioned is an "amped-up fuchsia" amplified finish lipstick (source). MAC Party Parrot is a "bright red-pink" matte finish lipstick that came out with the Iris Apfel 2011 and Strength 2012 limited edition collections. These two shades are extremely similar to each other but differing slightly in undertone and finish. These are neon reddish pink lipsticks that practically wears itself.
1) Milani Flamingo Pose ($5) - Flamingo Pose is the perfect mix of MAC Impassioned and Party Parrot. It's a dupe of both lipsticks but it's not identical to either. Impassioned is a touch cooler and darker than Flamingo Pose. Impassioned actually looks like the duller version of Flamingo Pose. Party Parrot has exactly the same color as Flamingo Pose but Party Parrot is completely matte and Flamingo Pose has a decent amount of glossiness. It's closer in finish to Impassioned but closer in color to Party Parrot.
