reverse speedo 

When a man start shaving his pubic hair and then continues to expand the shaved area until it looks like a pair of speedos of no hair.

I walked out of the bathroom with what looked like a reverse Speedo. I had become so caught up in the clean-up effort that I had totally forsaken any attempt to blend. Each swath removed led to another that seemingly needed to go. The end result was a totally unnatural ruler-straight line of hair running across my waist about two inches below my belly button and oddly smooth upper thighs.

"Oh man, Eva was so hot that Chris told me he went home, busted out the croc butter and reverse speedbagged all night."

Reverse speedos 

This is wash day plus two. Running out of briefs (smalls) necessitates urban swimming in your speedos and as we all know they are basically a 'reserve' pair of briefs for this occasion. Reverse speedos are 'stretching the envelope' of the concept into another day!!

The Dude is such a lazy slob, rather than nailing his laundry last night he's doing reverse speedos today!
