Panic and run away.
Panic and try to run away but get taken down by palm howitzer fire.
FTFY.
1st I leave a wet spot on the ground and in my undies then I runaway to the closest juggy all while screaming and giving the Team America I'm in trouble signal
Never not funny ... (I don't think I said that correctly
)

Usually?
This

or this

depends on character
On host with no stagger, facepalm and run away.
On host with single target stagger, frown, back away while shooting to take them down one by one.
On host with AoE stagger, act normally and kill them all
Off host with heavy lag, facepalm and run away mainly to move into at least mid range.
Off host with some lag, act normally and try to kill them all
Off host with minimal lag, laugh and kill them all.

Generally when this happens, I'm playing as a Volus, which aren't good enough for your average phantom, and thus they ignore me for a second or two:
I cloak, and run right through the middle of them firing my venom and spam any power I can.
With any luck the far sexier paladin is a few seconds behind me, and draws their attention.

Human soldier with claymore: Find RHA. Then two phantoms dead in two headshots in the best case. Else, throw grenades to make them bubble and then headshot. If nothing works, whip the cobra.
I put on my robe and wizard hat.
I put on my robe and wizard hat.
I set upon them with a vengeance!
Dexterity die!?
I toss a geth flamethrower turret, overload, run backwards while shooting them with my executioner and reload-canceling with overload.
I kill them.
KROGAN!!! STYLE!!! = maybe some phantoms find a brutal death
S.I. + Harrier = what phantoms?
The others = nuke them to death!!!
Wish I was playing my claymoar/Jugg.
Shadow, cloak and SS to pick THEM off one by one for a change. Or play juggernaut.

Kite them on over to SlimJim
Judging from a recent game I get melee'd 'til I'm dead...or someone shows up with a missile launcher. Either/or, it doesn't go well.
Venom with the Cabal! Now that's VENOM!
