derives from holding up
three fingers to form a W.
The W usually represents the slang term "Word" and sometimes "Whatever". "
Threes" can also be used when someone says something stupid and you reply "What?" but instead, hold up three fingers and say, "Threes."
For example, "
threes" can be used in situations like these:
Friend: "I'll meet you at the
dining hall at 3, I have class now."
You: "
Threes"
or
You: "She just cheated on me with that dude. But it's okay I'm move on and I'm gonna get with her best friend. Threes Bitch!"
and finally,
Friend: "My dog is black."
You: (must hold up
three fingers in this case) "Threes to you making that dumbass remark."
