Sexual intercourse that takes place up against a wall, usually furtive. Most often takes place due to not being able to share a bedroom with one's love when visiting family for the holidays, because of strict parental guidelines, regardless of one's age.
While everyone was in the dining room feasting on the Christmas goose, Mark and Christine snuck around the corner by the den for a wallbanger before dessert arrived on the table.

Raucous sexual intercourse resulting in a bed headboard hitting the wall loudly and repetitively. Often a nuisance to people in adjacent room(s). Frequent occurrence in hotels and motels.

Downed a few wallbangers before heading to the church, and suddenly I had no qualms about getting married anymore!
