suzu head
A running gag in Seitokai Yakuindomo where Hagimura Suzu's short stature causes her to appear out of frame. The top of her head is often the only thing visible, and is usually marked with an arrow with "Suzu Head" on top (or sometimes simply "Suzu Head" directly on her hair).
Can also be used for any parodies of this (e.g. post #2565911).
