A common insult, often abbreviated to sux on the interweb, used when describing a bad performance.
Mistakenly thought to refer to a blow-
job, "... sucks" refers to the fact that the dutch noticed that certain boats "sucked"
water and this would result in a little wave at the back of the
boat. The larger the wave, the slower the
boat would go; and at a time where there was a big issue with pirates and other naval threats, the fact that a boat "sucked" meant that it performed badly.
