Walking Hard-On 

Having an erect penis when standing up and/or walking/running. The results are usually highly visible and embarrassing. (See pitch a tent.)

Our secretary is so f*cking hot that she gives me wood all the time. She caught me with a walking hard-on the other day. I was so embarrassed.
