A sex act performed by
two persons, in which a male participant rubs their erect
penis back and forth along their partner's intergluteal cleft (ass crack). In the midst of passionately hotdogging, the
couple link arms at the elbow, using them as leverage to 'row the trench'.
Man,
Steve really chafed my stink star while we were
rowing the trench.
It's important to properly
lube the glute luge before rowing the trench.
