chach/chachi 

A guy into the following: his fraternity, spring break, Dave Matthews, sports bars, chain restaurants, Abercrombie and Fitch, thinly-veiled misogyny. From the character "Chachi" of "Happy Days" and "Joanie Loves Chachi" fame. Oddly, Chachi himself did not fit the above criteria; yet, he embodied the essence of trying way too hard and having no fucking clue.

At my cousin's bachelorette party, we ended up at Senor Frog's - full of chaches. I had to bail.
