I actually did this alot in mk 9 when i would lose to raiden and kung lao, but not in a "im gonna do it better" way, i did it in a "i'm gonna spam the same 2 strings and 2 specials you've done for the whole match, see how you like it"
This is particularly funny when you main Ayane & Christie lol. Yes, the only reason why anyone wins in DOA is because of the character and never because of player skill -Code of the scrub #67
Only when the character themselves is a salt-pick. It's a common occurrence when I beat someone in a lobby only to have them switch to Christie on their second go. I beat them again, then pick Christie on the third match and win again.
Happens a lot with Momiji as well, but I'm not lame enough to pick her (even out of condescending irony).
