A puhpfest is when a slew of puhps converge upon one location and hold some kind of party, or 'fest'. Nearly everyone at this 'fest' will be a puhp, so if you find yourself at such an event, be kind and excuse yourself promptly. If you do not, it is presumed you are one of them, and unfortunately, you will be labelled a 'puhp' for life. Life.
I went to MJBs party this weekend....total puhpfest.
