Otherwise expressed as "pee-pee tent," the penis tent is a communistic gathering under the sickle and
hammer. It has
next to zero sexual under-intonation; however, in the right context, it is an extremely suggestive form of flirtation.
The building of the penis tent required multiple men. Note the past tents. Formally, this
act signified the creation of stonehenge.
Now, it is nothing but a metaphor for a
male gathering.
