Ketchup boy 

A ketchup boy (or girl) is someone who lacks a sophisticated and/or well rounded palate. This person prefers the most basic of condiments, ketchup, above all other condiments.

Naw, Sean won't try that new restaurant; he's such a ketchup boy there's nothing on the menu he'd try.

Ash Ketchum 

Ash is the "hero" of anime series Pokemon. I'm sure you've noticed that his last name sounds like "Catch 'em", a phrase used often in the show. He is incredibly dim, idiotic, and has no idea how to raise his Pokemon. If he didn't have Misty and Brock traveling with him he'd probaly be dead.

Ash Ketchum sucks at battling but somehow always ends up getting a Gym Badge.

Ketchuphobia

The fear that a person wearing a white shirt gets when eating a hamburger, hot dog, chicken, etc., that has ketchup.

"It's Jim's lunch break, and I think he has ketchuphobia. He has barely touched his Quarter Pounder, probably because he has that presentation at 3."

A grossed out statement when a girl wants to have any form of sex with you on her period.

Guy: HELL NO! I don't like Ketchup on my lettuce.

tapping the ketchup bottle 

The day after a girl has finished her period, then has sex, the next day she bleeds a little more.

I had sex last night with Jon and this morning I was bleeding again I guess he tapped the Ketchup bottle.

My husband was tapping the ketchup bottle to get the last bit out. I was very happy he did!

We were tapping the ketchup bottle and the kids woke up.
