When one guy is sitting down two guys approach him from opposing sides. The guy in the middle then proceeds to pull out the dicks of of the other two and stroke them off while he sucks his own dick. Thus appearing to look like an anteater doing the doggy paddle.
"Me and Dave were over at Jimmy's last night, shit started to get real gay and next thing I knew, Jimmy was doing the swimming anteater on us."
"Nothing gay about a Swimming Anteater, that shit is just innovative."
