Unsuspected 

Someone or something you don't think is at fault.

Amy is an unsuspected kidnapper.

Unsexpected 

When someone or something is unexpectedly sexy.

That guy at the bar? Pretty average. Until you saw his quirky, patterned socks. They turned him into a total Sexgod. That was unsexpected.

Unsuspecting brown force

When you’re going to use the bathroom (#1) and you let out a fart and shit unexpectedly comes out. Similar to a shart, but you’re not wearing pants and you’re sitting on the toilet.

Can also be referred to as “brown thunder”.

Person 1 “BRB bro - I gotta go take a leak!”

Person 2 “ Okay I’ll wait here for you.”
15 min later..*person 1 returns*
Person 1 “ Sorry I took so long - I thought I just had to pee but I got hit with the unsuspecting brown force!!!”

HELL HATH NO FURY LIKE AN UNSUSPECTING MULE ABOUT TO BE SADDLED WITH TWO 10-FOOT KAYAKS 

The pinnacle of anger that has been attained by a jilted broad. Trust me, this is the most pissed off state of mind that a woman can get into...perhaps borderline homicidal...if not homicidal...so take heed, dawgs!

After being caught by his wife with his pants down with the neighbor in the back seat of his Chevette, Ray was subsequently "bobbited" and then castrated by his ball-and-chain during her storm of fury. Hell hath no fury like an unsuspecting mule about to be saddled with two, 10-foot kayaks.
