That’s short for CHESTER THE FUCK UP (CTFU), which is a term coined by a friend of mine from high school. Actually we did not attend the same high school but he attended the “brother” all-boys complement to my all-girls Notre Dame.
CTFU was developed in response to an invitation to a pity party I was having for myself on FACEBOOK. If you know anything about Chester, Pennsylvania; Delaware County Pennsylvania; the non-affluent** suburbs south of Philadelphia, etc. no further explanation is needed.
Incidentally, I grew up in the EAST END of Chester but my elementary school, ST. HEDWIG’S, was in the WEST END. Bob, who coined the term CTFU went to ST. ROBERT’S, located in the East End. Most of the friends that I made when I moved on to high school were from St. Robert’s. (Go Bobcats!)
