verb:
To stalk someone on Instagram.

This is a development from the traditional Facebook stalk, as there are many more users that will allow their Instagram account to be public, and therefore open to Instastalkers (noun).
I know she goes to the gym, because I instastalked her.

I've made my Instagram account public, so everyone can instastalk me.
