Viktor o - o

Okay so i dont know if this is something I heard but when i had just killed Miss Fourtune and went into a bush i was spamming his laugh which is ctrl 4 and one of the laughs was very odd it seemed deeper and sounded like everyone on the rift could hear it I asked my team and our support Leona Told me she heard it and she was at the base buying items. She told me it might be a champion teaser or something but i don't know can anyone else tell me if they heard this strange Viktor laugh to or am i just imagining things o - o
