Nobblecock: when one grabs the stem of the penis so hard that the bellend swells up and turns red like a balloon.
When i was in the shower i strangled my penis and the bellend went red, it looked like a nobblecock.

I love choking my girlfriend with my nobblecock.

I bet that kid has a dirty nobblecock.
