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.
