fuck it it's sophomore year 

The year of high school that is just there. You are not a freshman anymore, but you are not an upper class men yet. Because sophomore year is pointless and just simply does not count for anything, just fuck it. Fuck shit up like there is no tomorrow because it does not count and nothing matters. It's like a free year in high school where you can just do whatever you want.

Person #1: Hey wanna get fucked up tonight
Person #2: It's a Tuesday night
Person #3: Fuck it it's sophomore year

Sick-for-it-itis

This is used to describe people who exclusively use Sitka branded gear, and think they are better than everyone else because of it. Sitka's motto, "sick for it" is a common hashtag people use on social media when posting about Sitka gear, hence the disease "Sick-for-it-itis" . People that suffer from this disease are usually cocky, and look down upon others because they spend thousands of dollars on mediocre, at best, gear.

"We knew Bobby had a strong case of Sick-for-it-itis when his entire instagram account consisted solely of Sitka gear pictures and #sickforit hashtags."
