When a person (usually a female) does something really trashy and is not only proud of it but brags about it like it's the greatest achievement of their life.
She said she had a one night stand and didn't even know his name, she's such a trashbrag.
Any packaged conglomeration of trash used as a weapon against a motorist. A trashogram may have insults written on it. It is generally thrown at or into the vehicle of an erratic or dangerous driver.
"that ignorant squack just pulled in front of the semi, and cramped on the binders!!"
When the popular social media website becomes trash and you feel like it is eating up a lot of your important time or invading your life then it becomes “Trashagram”.
Why botherposting about the rain in your area over trashagram ? People have weather apps for that.
