PNPKDUHJERK RADICALSYMBOLIC
JERK RADICAL ALERT- although the kanji means 'mouth' the radical sometimes means "box". Irritating but not totally a hassle when you consider that it looks more like a box than a mouth, anyway.

Also, jukugo with 口 tend to be KUNKUN for some reason.

Onyomi

KOU, KU

- as in, "My KUchi on your COLON . " Disgusting? Yes!. . . but try forgetting this ON-yomi now.

Mnemonic

You can think of this as an open mouth, just yelling at you . Always yelling! Again with the yelling JESUS WOULD YOU SHUT UP ALREADY JUST SHUT UP. YEAH THAT'S RIGHT. JUST CALL THE COPS. GREAT!
