Philly Nalbone 

the act of plunging one's erect penis into a nalgene full of warm cheese wiz and/or Philadelphila cream cheese

Since my girlfriend was out of town a Philadelphia Snowplow wasn't in the cards so I decided to treat myself to a Philly Nalbone instead.

The act of plunging one's erect penis into a Nalgene full of warm cheese wiz and/or Philadelphia cream cheese.

My girlfriend was out of town this weekend so instead of engaging in our usual Philadelphia Snowplow I had to resort to the ole Philly Nalbone.
