The letter a but there's too many Combining Characters. The combining characters make this "a" seem very tall.

Guy 1: wtf
An abomination of letters that comes from typing qwertyuiopasdfghjklzxcvbnm with three extra m's. You probably found this while you were bored, just sitting there pressing the m key repeatedly until you get to a sequence that isn't defined.
Guy 1: I've just been here, aimlessly pressing m. I've gotten to qwertyuiopasdfghjklzxcvbnmmmm, and there's still this definition. Should I really continue this meaningless activity?
Guy 2: wtf
when you are litterally too bored for freaking qweasdzxcrtyfghvbnuiojklmp and you just can't help yourself. You probably typed in "plijnygvrdxwa" and then typed the rest of the keyboard in the same way, just the other direction. This is the pinacle of human boredom.
1: I got so freaking bored i had to type qweasdzxcrtyfghvbnuiojklmp!
2: i have more boredom, thus i typed plijnygvrdxwaqesztfcuhbokm!!
