look up any word, like someoneelsie:
 
1.
(n): that time period after which you return to your normal routine of work or school usually after the weekend and you see an extraordinary amount of people have received a haircut; most commonly observed after breaks or three-day weekends
Person A: "Dude! There's like three people in this class that got a haircut this weekend. WTFFFFF"

Person B: "Yes, and it's not surprising; President's Day often brings about the phenomenon widely known as Haircut Weekend...and thank you for noticing MY haircut...douche."
