When a guy finds out a girl has recently broken up with her boyfriend, and tries to have sex with her, he becomes a Tisshoulder.
This is because he poses as a 'shoulder to cry on' and has a metaphorical 'tissue' on his shoulder, representing his 'caring' nature.
Person A: Hey I heard Mandy broke up with her boyfriend!
Person B: Oh no, better cheer her up with a quick shag!
Person A: Man, you're such a Tisshoulder. Bad attitude man.
