A Half-Arsed Sofa
Bash-Off. Commonly believed to be the most depressing of all self-pleasuring, the HASBO requires the use of a sofa or settee (and in some circles, possibly a chaise-longue) and generally occurs having woken up in the early
afternoon, with minimal possible effort and with no upper-arm movement.
Other common features include a hangover, not having
washed for several days, being unemployed, bachelorship and a deep-rooted apathy towards social norms.
