1) v. to "like" every image in one's Instagram feed in a single, continuous session without regard for the quality of or interest in the content.

2) v. slang term used by millennials to describe a sex act by a male who prematurely ejaculates.

It took me forty-five minutes to Instablast, since I hadn't looked at my Instagram account in several days.
