Raincoat
From CWCki
"Raincoat" is a euphemism for a condom. It figures into one of the later scenes in Sonichu #7 as a pun.
Aside from promoting safe sex and justifying premarital sex, Chris draws his male characters with condoms to censor their pickles.
Chris had a box of chocolate flavored condoms that he purchased to be prepared for his first time. Chris has given a few different dates for when they expire; some time in 2010 [1] and January 2013 .[2] Either way, the condoms will expire having never been used.
