When adolescents who are grounded or banned from a party bounce. Usually a highly planned event. People will also sneak out for fun if they're grounded or not. Many sneak out to meet friends and party, but make sure they don't drink/do drugs or they wont be able to get back in. Even more people sneak out to meet boyfriends/girlfriends and make out or romp. If your rents find out you screwed.
1.Me and Lisa went out to a big party. Oh yeah, we had to sneak out.
2. Me and Jeff sneaked out and fucked until sunrise, then I climbed back into my window.
