When you are taking a shit and your dick touches the cold porcelain at the front of the toilet, causing discomfort and in the case of public toilets, absolute disgust.

Best referred to as "TBD" in mixed company.
I was taking a shit and I got toilet bowl dick again.
Man the toilets in the mens washroom here are just terrible for TBD.

FUCKING TBD!!
