1. When a (usually) young man masturbates or receives a hand job, and ejaculates all over his own shirt. He then has to self consciously walk around with a cum stain on his shirt, unless he was at home or had the foresight to bring an extra shirt with him.

2. Sloppily and shamelessly enjoying oneself without consideration for appearance or the feelings of others. Can be male or female

cum on the shirt (n) is another version of this saying
bob went to sally's house after school. she didn't want to blow him, so she tugged him off and he came on his shirt. Then he rode the bus home and felt hella awkward, since he didn't have a coat.

Suzy was being such a drunk ass at that party last night, she definitely came on her shirt.

Get the came on his shirt mug.
This phrase was developed from the 'Rock out with your cock out' genre.

It refers to 'The Walk of Shame' which people do early in the morning trying to avoid being seen returning home from a drunken or regretted sex session the previous night.
1- "Look dude there's Steven!"
2- "Haha! This is the reason I stay up all night smoking and drinking coffee - to catch people doing the walk of shame!"
1- "He came out with his shame out."
