It seems collided is the least picked option, but I've grown to really like it and find it really funny! The idea of yeeting myself into something is a silly visual and seems like very aggressive love in a way. With friends too, I've been kind of interpretation it as a very dramatic aggressive bonk depending on the context. No hammer? I'll just use a full on asteroid.
It's gotta be the Space Whale for me. Between the cute plush and my being a member of the International Space Cetacean team which is themed around whales, it just feels the most appropriate and fun to use.
