The “Ilgbt+” community is an altered acronym coined by incel groups online as Incel, Lesbian, Gay, Bisexual, and Trans+ in an attempt to insert involuntary celibates into the LGBT community due to both groups having “oppression” despite that oppression being unequal and even incomparable in most circumstances.

The I in front of the rest of the acronym is due to incels believing that because their experienced oppression is worse than that of the rest of the LGBT+ community, the I deserves to be in front of the original acronym.

The LGBT+ community however has argued against this acronym in almost all circumstances however, due to the misogynistic and homophobic nature of most Incel forums, thus making the acronym ultimately unofficial. It is still not entirely uncommon to see this acronym used by incels, however, and will most often be seen in attempts of gaining sympathy and/or hurting other communities. This acronym also contradicts the already-used I in the lgbt+ definition as intersex.
“Did you hear about incels trying to insert themselves into the LGBT community?”
“Yeah, they’re now calling it the ILGBT+ community. I thought incels hated homosexuals though.”
“Doesn’t the I already stand for intersex?”
“It’s not like they’d know.”

In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.
"Shit...the sales director chewed me out on the sales call this morning. He's totally pissed that I have nothing in my pipeline. I've been focused on this one whale for so long that I haven't had time to prospect for normal-sized deals."
