I've submitted in Boobs AND booty AND legsetc. As long as the meme fits the stream theme the mods don't care.
It's best to post in one and then submit to another 1-2 days later AND use the Spacing option to make a minor change. (Then it's likely to get more upvotes, because many people follow more than on of those streams and they won't consider it just reposting for votes.)
HOWEVER, if you're ALSO going to submit to FUN, DEFINITELY submit there FIRST and WAIT until it features. THOSE mods DO reject recent reposts.
