In everyday English, obscene words like "fuck" and "hell" have been somewhat semantically bleached into intensifiers. For example, "fucking ridiculous" and "weird as hell" are common idioms that aren't considered particularly obscene in context.
In Greek, I would translate these intensifiers with a particle like δή. But what's the Latin equivalent? For example, if I want to paraphrase Horace and say "seize the fucking day" (intensifying carpe diem), what equivalent can I use?
A common way to intensify a phrase in Latin is to place an intensifier on its verb. An intensifier is a prefix, often a preposition or some other adverb, placed on the verb which can intensify it.
In English, we use intensifiers all the time, but they usually follow the verb. For instance, the verb "tear" (rend or rip) can be intensified by saying "tear up". You have to use some care with intensifiers, because they can also be used to completely change the meaning of a verb. For instance, "take up" is not simply an intensifier of "take", but a whole new verb.
Back to Latin. Carpo has several attested prefixed forms: concerpo, decerpo, discerpo, excerpo, and praecerpo. All of these forms are at least somewhat intensified, although they all introduce some change in meaning or at least emphasis in carpo, so you'd have to excercize some judgment in which of the five you'd care to pick.
If you don't care for any of the attested forms, you might want to coin a new one. I can't help but think of succerpe diem, (grab the day from underneath, from sub+carpo). It reminds me of a not-very-polite and mildly obscene idiom in English (Grab it by the b-lls!), which is, however, quite emphatic.
As much as it pains me to say this, because of my stance on profanity, there is a book that might benefit you. It is called X-treme Latin: All the Latin You Need to Know for Survival in the 21st Century, by Henry Beard. In it you will find some rather colorful phrases, some of them profane, some not, that can be used in many situations. It is a hilarious book that also teaches the Latin word for NAZI. Below is the Turabian reference, which should help you find it (try your local main branch library).

He also has similar books which also include slang and other terms that might suit your needs, but I would start here. Happy hunting.
