Instastalk

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