An Islamic outburst is when a boyfriend gets aggressive with his girl because of jealousy or anger management issues, sometimes physical.
When he gets (over-)
protective of his girl and starts to lash out at her or a guy she's
talking to.
Or even just when he gets extremely upset (
exploding) over something others think is not as big of a deal.

It stems from the stereotype that all Islamic men are aggressive and see women as their property, so some peeps I met put these two words together. I've never seen it be used where it applies, but rather:
GF: "I shouldn't talk to
you like this,
I have a boyfriend."
Uninformed random bloke: "He's not healthy for you babe, what with his extremist ideology and all these Islamic outbursts, he's definitely a terrorist."
Or
Uninformed random bloke: "Hey girl, can I have your number?"
GF: "No, my boyfriend and I have made agreements regarding that, and besid-"
URB: "I SEE HOW IT IS, that guy of yours got you dancing
like a puppet, I guess if you don't do as he says there's no avoiding his Islamic outbursts!"
