Egypt. Syzygy. Callipygian. Others?
“Happy”, “trippy”, “sloppy”, and others of that sort.
Iggy?
Or maybe I am not a word. 
baggy, buggy, doggy, and so on…
Eggy, figgy, jiggy, saggy…
Gypsy, but only when not capitalized: gypsy.
Likewise gypped. w00t, 4 in a row.
Both of which derive from the OP’s “Egypt”, of course.
Add “soggy” to the “-ggy” pile, though I suppose there’s no real need to try and list everything in that pile.
crappy
zygote
Only if written in cursive, and then only if your z has a lower loop.
nm.
pygmy
There’s “pygmy”.
And while I was checking on that one, I stumbled across “pygostyle” — “a triangular plate formed of the fused caudal vertebrae [ of a bird ], typically supporting the tail feathers.”
Also “pygidium” — “the terminal part or hind segment of the body in certain invertebrates.”

If something were akin to being gypped, would it be gyppy?
Most consecutive ascenders? Breadth?
Brightly have I added to your little ascenders list. But being from Seattle, they come easily.
