Saying “wearing condoms suck” is actually setting me on fire because the verb “suck” fails to agree in number with its subject. In this construction, “wearing condoms” functions as a gerund phrase, which, despite including a plural noun, acts as a singular subject. The word wearing is the head of the phrase, and gerunds (words ending in “ing”), by grammatical convention, are treated as singular nouns. Therefore, the correct verb form should also be singular: “sucks.”
