A failed shithawk. Somebody who lurks in a chatroom or a forum waiting to snipe another user, but is ineffective. Thus, the majestic hawk lining up a shit on an unsuspecting target below lets out such a small squeeze from the cloaca that only a tinkle is produced. The target feels a slight drizzle and wonders if a finch just pissed on them.
"hey guys this guy just tried shitting on my day, but i only felt a tinkle. it was refreshing. thank you pissfinch!"
