When two men or two women both enter separate bathroom stalls next to one another and have a general conversation about life. It's never about the situation of partaking in a soash or the shitting itself... just a generalized conversation.
This is mostly done among high school students at a set time, during class, never at breaks as you need your privacy when soashing. Although soashing is usually planned it can occur randomly with a friend you just happen to meet while taking a shit.
Dude Bro 1: Hey bro, 11:30 soash?

Dude Bro 2: You know it!
