ready to party!
It means like lets start the fight (boxing match).
To fight. As in, get ready to rumble.
they usually say it when an animal is getting ready to have babies (having sex) but i think they also say it when a human is
"How are you getting ready?"
Getting ready - making preparations
had a dream someone was getting out of jail
if rumble you mean fight and sentence you mean statmane then yes
Getting topped by someone means to have them fell your boobs
it could mean your fertile and getting ready for ovulation.
Getting off--to become sexually aroused and have an orgasm, either with someone else or by yourself (masturbating) Going with someone--usually means to date or see someone as a boyfriend/girlfriend Depending on where your from, getting off with someone can mean snogging them(kissing a lot basically).
Basically, it means "get ready." If you tell someone to saddle up, it means get ready or prepared.
How should I know? Go ask someone else.
