A shmunch is a brunch between 2 people after having a one-night stand, often preceding the walk of shame going home. Shame + Brunch = Shmunch. A shmunch is typically recognizable at a cafe or restaurant because the shmunchers are dressed in clothes from the previous night's affair (i.e. sequin mini-skirt and high heels with bedhead and messy makeup on a woman, and overly dressy and wrinkled clothes on a guy, mixed in with bedhead and morning breath)
Dude, I'm shmunching with Anna from last night.
