Gamer's Gap 

The shape that a gaming headset or any type of over-the-head headphones makes in your hair after a gaming session. This shape can also occur when you are listening to music for a long time without taking the headphones off. This usually occurs in people with shorter hair

Gamer: I didn't take my headset off for four hours and my hair got a gamer's gap
Gamer 2: I hate that bullshit it makes me look like an upside down cereal bowl!!

Old Man Gap Year 

The time off between your last day of work and your first day of retirement, typically spent drinking, golfing, fishing, or drinking. Usually occurs when you’re not quite ready to retire, but you can’t stand your fucking job for another second.

I saw Fred at the golf course again yesterday. Did he retire or is he just on his “Old Man Gap Year”?
