1. Anything meant to make a 'romantic occasion' more meaningful than it is, while killing all sense of romance.
2. Anything that makes you embarrassed of the person you're courting.
3. Anything that makes you want to dump someone's ass.
'Romantic bullshit' consists of things that detract from romance - objects like gross scented candles which induce suffocation; or clichéd thoughtless things like lousy poetry that make one of the parties involved feel awkward; ie, "roses are red, violets are blue, I have a gun, so get in the van."
