Sickoes...

[Kerim]

What does the "sickoes" mean? Is it a plural word?

[Casiopea]

Kerim, I found this entry in an on-line dictionary:

sicko (noun) Slang pl. sickos
A deranged, psychotic, or morbidly obsessed person.
(dictionary.com)

But Dictionary.com says "its plural is the sickos", not sickoes.

[Casiopea]

Right. They are variants.

Nouns ending in o preceded by a vowel form their plurals by adding -s to the singular: cameo, cameos; duo, duos; studio, studios; zoo, zoos.

Most nouns ending in o preceded by a consonant also usually add -s to form the plural: alto, altos; casino, casinos; ego, egos; Latino, Latinos; memo, memos; neutrino, neutrinos; poncho, ponchos; silo, silos. However, some nouns ending in o preceded by a consonant add -es: echo, echoes; hero, heroes; jingo, jingoes; no, noes; potato, potatoes; tomato, tomatoes. Some nouns ending in o preceded by a consonant have two plural forms (the preferred form is given first): buffaloes or buffalos; cargoes or cargos; desperadoes or desperados; halos or haloes; mosquitoes or mosquitos; zeros or zeroes.
