Played Poppy ADC once, with one of my friends going support Mundo. We were against a Lucian/Sona combo. Think my other friend was messing around on some weird jungler (also definitely off-meta) that I've long-since forgotten.
Somehow, we didn't actually lose lane very hard, and my favorite memory is the only one I really still have from that game: I was chasing Lucian after I caught him messing around in our bot lane, trying to push the tower. I started the chase from the Purple tri-bush next to the downed tower from much earlier, and he took off, kiting me as I relentlessly pursued him. He eventually made a mistake: He stood near a wall while I was in tackling distance. So I leapt from my position, and FINALLY got to start hitting him. By this point, I'm at about 300 of my 1600 HP, and he's at full before the tackle. After the tackle's stun took place, I hit him with a Q and went to town. He died and I stood at 200 HP left. He then complained that Poppy was OP, despite the fact that it was his own mistake that killed him and the fact that him kiting me practically forever totally didn't feel like complete BS to me at all or anything.
Still though, we managed to win that one. I don't know how, but we won. And that chase had a glorious end.
