sober sneak

"quietly moving around places you aren't supposed to be with someone you aren't supposed to be with while in a state in which u are not under the influence of any intoxicating substance"

I quit drinking but still want to have fun, let's sober sneak later while your husband is at work.

Sober-Sneak-In

A guy comes to a party late after everyone has been drinking for at least an hour. He finds a girl who's clearly had to much and takes her to a secluded place to have sex.

Did you see Colton at the party last night? He came really late, and did that girl who was about to pass out.

Colten used a Sober-Sneak-In to get with the drunk girl.
