However, you learn a lot more about a person once you live with them, and the roommates know each other better than anyone.
MTV News recently caught up with most of the girls and guys of "Jersey Shore," and since it's the final season of the show, we figured now was as good a time as any to see if they would spill the juiciest secrets about each other.
Most Likely to Hook Up With a Grenade
There has been no shortage of awkward and questionable hookups throughout the summers at the "Jersey Shore," and after late nights of partying at Karma, the roommates have been known to put on their beer goggles.
But is there one person in particular who just can't help him (or her) self to hook up with a grenade?
"Mike," Sammi "Sweetheart" Giancola, Jenni "JWoww" Farley and Deena Cortese all said in unison.
And it seems that Ronnie Ortiz-Magro would have to agree. "That's pretty easy: Mike. I'll take Mike for 200, I will not pass go."
Most Annoying Drunk
There is always one thing present in the "Jersey Shore" house, and that is alcohol. An abundance of Ron-Ron Juice is usually consumed before a late night at the clubs, but after hours of drinking, there is also one person who tends to be a bit obnoxious when tipsy.
"Me," Deena said without hesitation.
"I would have to agree," Sammi added.
It seems like the girls picked the right answer, since the guys also unanimously picked Deena.
"I'm gonna say Deena. She cries when she's drunk," Pauly D said. "We actually came up with a name for Deena when she's drunk. It's 'Meana.' "
Best-Kept Roomie Secrets
There is a lot that goes on behind closed doors of the shore house that viewers don't always get to see, but both the girls and guys had no qualms about sharing their housemates' most embarrassing secrets.
"Pauly has these little floss things that he puts in between his freakin' teeth, and he just throws them everywhere," Deena said. "And you find them everywhere used, and he doesn't care."
And according to the girls, it seems Mike "The Situation" Sorrentino only cares about keeping his face clean, but not his bed sheets.
"I'll tell you something, Mike washes his face like 40 times a day," Sammi said.
Deena added, "Mike never washes his sheets."
"Never washes his sheets, but washes his face," Sammi said.
"Or his towels for, like, two months," JWoww added.
Not so fast, girls, it seems the guys have a shocking tidbit about JWoww.
"Jenni takes wicked poops. We always thought it was Ronnie, but it wasn't," Pauly said, laughing.
"Yeah, there was something going on there for sure," the Situation said chiming in.
"Ronnie's like, 'What are you talking about? I didn't even go in your bathroom,' " Pauly said. "I didn't believe you until now."
Don't miss the final season of "Jersey Shore," which premieres on 23 October at 10.30pm (WIB), 11.30pm (SIN/HK/PH) on MTV Asia.
