An ugly girl who thinks she is good looking and is craves cock in the mouth.
Wow Bryan Abous mom is such a Dick Troll, she gave head to Mike Tyson back in high school.. and she swallowed.
Particularly unattractive girls that show up to a party with the intention of getting a guy drunk and having her way with him. Their desperation and foul appearance earn them the name, "Dick Troll".
"Hey man where's Jeremy?"
"He's wasted. I think one of those dick trolls took him home."
Laughter ensues, at his expense.
