I Am Pleasant Damn It Christmas T-Shirt 

The phrase "I Am Pleasant, Damn It Christmas" when printed on a T-shirt, usually carries a humorous, ironic, and slightly mischievous meaning, especially within the context of the Christmas holiday.

Analysis of the Phrase's Meaning

The phrase is a combination of a self-affirmation and an emphatic interjection:

"I Am Pleasant": This is a declaration about the wearer's disposition or mood.
"Damn It": This is an interjection that expresses annoyance, frustration, or sometimes just a strong emphasis, and is informal.
"Christmas": Placed in the context of the Christmas holiday.

The Humorous Contrast:

The core meaning lies in the contrast between declaring oneself "pleasant" and using the slightly "rough" emphatic term "damn it." This creates a witty tone, which can be understood as:

Affirming Festive Cheer: The wearer is proclaiming that they are in a cheerful, pleasant mood, and their "Christmas spirit" is very much present, even if they are dealing with some minor holiday hassles (like shopping stress, too many parties, or social obligations).

Light Irony: It can also imply that others might doubt the wearer's pleasantness during the busy season, and the wearer is asserting it back with a slightly defiant, humorous tone (e.g., "I am happy, alright!").

Concise Meaning: This is my Christmas spirit, in spite of everything!
